Jumping(bucking) RPM issue when tuning car

[shoblock]

I’m still new to all this so i don’t know how i would go about posting a datalog file and yes when i return to stock it runs perfectly. Which is why I’m so confused

Not trying to be Capt. Obvious, but when you switch it back to stock, you put the 2 bar back in, correct? It won't run right with a stock tune and a 3bar, AND it won't run right with a tune and a 2 bar.

and are you replacing the correct map sensor...there are two. The correct one is on top of the intake manifold.

Don't forget that stupid little hose that can blow off under too much boost (wastegate solenoid hose?). Once that little hose is off, the car will surge and then cut power repeatedly when under boost. At least, that's what my car did. It was subtle on a stock tune but I could feel it whenever I got on the gas. I bet it would be terrible on higher boost tune. (and mine never set a CEL)

I’ve actually been looking into BCB but I’m nervous that if i purchase a tune and load it, it might happen again so I’ve emailed them and tried to get their knowledge on it and the response time is very long. Any opinions on which you think is the best bang for the buck?

I have recently tuned with GH and their AO tune. Matt is super helpful. It is my first and only tune and I have absolutely 0 complaints. Definitely made a difference from stock. I have heard good things from AJturbo and Unleashed also.
