Spitting and Sputtering on Boosted Integra

My friend has a boosted 95 SE with a 50 trim blah blah blah. When he is driving as soon as he hits full boost (11.7psi wastegate spring) his car spits and sputters. He is running stock injectors and MAP with an SAFC. It is a 50mm wastegate and we can't seem to figure out why it's doing this. Any help would be appreciated. Any info needed just ask!

TIA

could be to much fuel or not enough its the tune... the stock maps are suppose to be good for 10 psi or so, but i have used a stock one on 15 psi...

and i just noticed your running stock injectors which probably means your using the stock fuel pump as well..

yea stock both. when in a higher gear 4th/5th it hits boost and throws a code also. Do you think injectors could be the problem?

Does the search button or FAQ mean anything these days.

Spitting and sputtering, because you are lean as **** and more than likely detonating the **** out of the motor. Throws a MAP code because you if you have a map bypass it isn't working or you don't have one, and in that case that is the problem.

1) Get bigger injectors.
2) take out that damn SAFC.
3) Get good management.. crome/neptune/uber/hondata.

Take it to a tuner, problems fixed.

Yes. I found that mine wouldn't handle anything more than 8 psi on my stock pressure and stock pump. So a 255 would be a good idea.
