7 psi wastegate tuning

[gtx3076]

So all my parts came in, RMM, crossover pipe, whoosh V3 intercooler, GFB DV+ and the turbosmart 7psi wastegate.

I e-mail dizzy and he suggested a 93 touch up and the E40 flash tune. I asked him if there would be revisions on the E40 flash, and he said one and done. I was a little confused about this, because somebody else was tuning on the wastegate and has posted updates with several revisions.

I would think with wastegate tuning it could be dialed in a bit more, am I wrong about that?

I bought full custom tunes to squeeze out what I could out of the stock hardware on 93 and E30, so I'm not feeling the recommendation to go with an OTS tune.

I recently received the E40a Flash Tune about 2 weeks ago and it's really strong through out the whole powerband. I still can't stop cackling like a Japanese school girl everytime i get on the pedal. I usually peak between 27-28 psi by 4k rpm and get 15-17* of advance timing. Boost seems to come on a tad later but it holds well to about 6.5k rpms. It is a one and done situation. After you upload to your ecu, Jason will have you send him 3 datalog pulls to make sure your engine is happy and that's about it. I was really surprised because I thought it would take more to dial it in, but it's spot on right out the gate.
