when I romp on it in second, and throw it into thrid, it will hesitate for one jump then get back into the power. I dunno what that is all about, but I'm pulling the plugs tomorrow to do a compression test and see if they are bad or not. I canttell what it really is. its like it starts to pull, then nothing for a split second, then it starts pulling like crazy again.

This is a B16 with a 48/60 at 12psi on stock internals. Joseph davis's map in the bin directory. I've also ot a boost leak, but thats a whole nother problem....gonna try and fix that tomorrow as well.

 

You have a stock map sensor?

 

gm 2 bar.

 

Had the same problem, tune'd it and gapped my plugs down. Haven't had that prob since.
