So I've had this problem for quite a while now (about a year) and for some reason waited till now to ask about it... But to the point...
So when I blew my stock turbo I threw in a 62mm River City non vgt, and promptly got custom tunes from matt to go with it. Now ever since then, most of the time if I just mash on the throttle, when it hits higher rpms, it will sound as if the engine is bouncing off the redline. Now if I roll into the throttle until I am just about to the floor, it doesn't usually do this, but overall hard acceleration will usually yield this strange occurrence. I had Matt try to tune to fix it, but it didn't do anything and I don't think the tunes are the issue, and I also got a walbro inline pump just incase psi was low, and now don't drop below 48 psi ever, but I haven't done anything else. What could this possibly be??
Thanks!
