This ZZP tune paired with the ZZP parts is truly unbelievable with this tune I was able to beat top-of-the-line cars like 5.0 392 and a SS multiple times if you don’t believe me check out the ZZP Facebook group and look up my videos Ceodrew Tune by Matt
ZZP tune with modifications
Matt is absolutely amazing. I have gone back in forth with him for tunes and code corrections with new performance parts. extremely assistive as well as prompt. I highly recommend ZZP for any LTG owner that wants to wake that thing up these guys are knowledgeable and helpful.
Matt answered all my questions. He's amazing. Car runs strong. Takes pride in safety and quality of your car
down pipe install
It was pretty straight forward. if you've done the pcm update, you just email your file to Matt if whatever part you've installed requires a tune.
The best of the best when it comes to customer service. Truly.
