dsxtuning.com website review

About 486 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.3 s faster on a phone.

7 images could be 750 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.7 s faster on a phone.

7 files are served with short cache lifetimes, so returning visitors download them again (247 KiB).

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (zotabox.com, Affirm and Shopify and others), adding 1.1 MB and 351 ms of main-thread time.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

zotabox.com costs a phone 166 ms of main-thread work and 548 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 132 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 long tasks block the main thread while loading, the longest for 175 ms. During a long task the page ignores taps.

Polyfills for old browsers add 16 KiB JavaScript that modern phones do not need.

11 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

4 KiB could be saved by minifying CSS.

Your largest element takes 16.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 16.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.0 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 1.9 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 85 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.0 MB in 244 requests on a phone: images 1.8 MB (26), scripts 1.2 MB (121) and other files 745 KiB (86). Under 2 MB keeps phones on slow connections fast.

5 images (1.1 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

3 images are downloaded at several times the size a phone draws them, for example Lambo-Engine.webp at 1,800 px wide, shown at 390 px. Resized copies would save about 318 KiB.

1 image further down the page (214 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.13 g of CO₂e: 136.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

13 elements hidden from screen readers can still receive keyboard focus.

6 tap targets are too small or too close together to hit reliably with a finger.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

14 visible links have no text or label, so screen readers cannot say where they go.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 10 characters: “DSX Tuning”. Between 30 and 65 characters leaves room to say what you do and for whom.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

8 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 93 pages on dsxtuning.com and 6 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/collections/air-intakes, /collections/cooling, /collections/chassis, /collections/engine, /collections/fittings and /collections/flex-fuel-kits and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.

/collections, /collections/air-intakes, /collections/cooling, /collections/chassis, /collections/engine and /collections/fittings and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

1 link from your homepage to your own site is broken, for example https://dsxtuning.com/pages/gm-dyno-tuning (404).

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

3 links go through two or more redirects, for example https://dsxtuning.com/account.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

dsxtuning.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

dsxtuning.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 196 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

DMARC is set to p=none, so mail pretending to be dsxtuning.com is still delivered. Reports are on, so moving to quarantine is the next step.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Meta Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 14 cookies, 3 of them by other companies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
