Well no **** but you said look it up on Garrett's site. I went on there to try and find some compressor maps. Surprise, it's not listed there.

a lilttle research goes a long way, t3/to4e 57 trim compressor map is in there

 

ok guys no offense but can we please stay on the original threads intentions please. lets not argue it up. thanks guys. i luv all of you still.

 

wellu said it runs out of breath what do you mean? the powr die off? i know that happends on the ms3, my bud has one and on the dyno there is no high end at all, is that what is going on? im sure the turbo is good for more psi if you want more power

 

Is the dyno reading jagged at the end of it? I am still unable to get full power out of mine. The car ***** out at about 5k whenever I am at high boost. the only thing in the log that i see is that the maf readiung stps changing at all when that happens. it pulls all timing my car basically *****, almost like a rev limter.

I have to stop trying to tune and looking trough everything because I need to pass inspectiona and the car hates to ready for evap. Maybe we have a simmilar problem.

Blow through or draw through?

 

sounds like your doing something like maxxing out the MAF, so it runs in the safest possible settings (IE pulling all possible timing). I know if you unplug the knock sensor, itll drive fine until you get into PE, where it then pulls just about all your timing.
neither of these sound like the issue the OP is having though, but the MAF one might be on you want to check out for yourself

 

I thoiught that too. But, on different pulls the maf levels out at different numbers. I would figure if i maxed it out it would be at the same reading everytime.

 

boost leak.
3 inch maf pipe is needed.

timing?
afr?
