Yea that’s ridiculous, I bought complete kit with their tune with the notion of eventually getting a custom tune after swapping to LT4 HPFP and injectors later on but may just do all that now and not even deal with Prochargers tune after hearing your horror story lol

I am not even close to the only one. Another forum user sent me their tune to try and it was labeled "procharger 5" so this is common for them apparently...

After having some time with my A&A kit, it does some pretty crazy lurching as well sometimes, usually when you hold it in mid-to high throttle but not wide open in the upper RPM ranges (like a spirited acceleration to avoid tire spin, but not full commitment to WOT). It's like the ECU can't figure out WTH is going on, and the car lurches like crazy. I think I need to get it down to Andy at A&A and have him give it a once over (he is not the original tuner...)

Yeah, mine did the same. When my tuner fixed it he said it was likely coming from the car falling back from one sensor to another for air2fuel... I'd have to ask specifically.

At about 60% throttle is where the bypass valve closes. Are you sure you're not just repeatedly opening and closing the valve? That will happen to my car and it will go from say 400 HP to 600 HP and back in a second..

That sounds kind of like what could be going on, but not 100% sure, this is the first time I have used a centri blower, so I need to learn more about the characteristics as to what is normal and what isn't. I can pretty much drive around the issue, but every once in a while it happens during partial throttle acceleration.
