Great service truly appreciate
After putting up with subpar tuning attempts for over a year when I saw remote tuning on the website for low buck cam I decided to let Joel do his magic. He is almost finished and wow I love driving my car now thanks so much.
Have not installed it, but the build quality is awesome
SBE Gen 3 5.3 with LBT cam and tbss intake. I have the T4 1.15 and it lights quicker than I expected.
Tool Works as intended...
It’s the real deal Holeyfield at an amazing price! Significantly cheaper than Summit Racing even with a coupon!
Easy install sounds awesome, performs awesome
Truck running great worked with Joel. Great to work with quick response
Quality parts at a good price, and fast shipping. What more could you ask for?
Love this product
Exactly what I needed at a fair price.
Love these cams, probably the 6th or 7th engine I’ve installed this kit into with awesome results.
Great tool worked great and I’m a first timer good investment for self and my buddies.
Works like a 30$ compressor woukd work
