Customer Testimonials

Hi Kelly,

I received the gauges this afternoon, fitted and tried them.  Excellent.

 Much more civilized than taking off the air manifold and using a flowmeter.



Just bought the kit from Kelly with PayPal at 20:50 pm, I received a notice 8 minutes later saying that the parcel is out for delivery and am given a tracking number,
It just does not get any better, not possible !!
Thanks Kelly,


Dear Kelly,

I am overwhelmed by the amazing job you have done for me on this boss.

The workmanship is second to none.


You Da Man……

Many many thanks bro.



I can't believe how fast it was to order your kit, I ordered last Saturday and received my kit today (Monday)  in Oregon, looking forward to trying it out this weekend.



Kelly my tools came today and they are beautiful! I want some more soon!



Your tools look excellent, better than the original factory tools, some of which are NLA.


your work is absolutely amazing ! It's to such an incredibly high standard.
The only downside is that it makes me want to redo all the parts I have already refurbished on my own car as suddenly they don't seem good enough anymore.

Received my SU HD8 adapter kits & gauges from Kelly before Christmas and they fit perfectly as expected. These are quality precision instruments.


Hello Kelly, Thanks for doing such an awesome job, you are a true artisan. AF

Wow, now that’s what I call service!


Hi Kelly,

​I'm just blown away at how awesome this kit works for me.  I can tell by the exhaust note, idle and driveway rev that it's different car entirely.  

​I will be posting this same info with a rave review asap this weekend.  You absolutely have my permission to publish this on your site, pics and review.

​Thanks for doing what you do and clearly you do it with pride.
