ok i was watching o 2 sensors when i get on it it goes to 900 mv. tcc goes to low duty cycle when i am at wot. it is at 96 percent most of the time though. im not sure i understand how duty cycle works. as far as tcc slip goes it actually goes negative when i get on it.

 

Are you speed density or MAF? Have you tried it without the meth? I had problems soaking the MAF with meth in boost even though it nozzle was downstream. Problem fixed when I went SD

 

I am SD. It is the same with and without the meth.

 

Dude you are too rich had the same problem I believe the MV need to be about 930 or so ck your AFR that's important!

 

When I read this, I thought it might be the transmission or TCC slipping. If you're locking the converter on WOT, you may be getting ready to lose the 3-4 clutches and/or the converter clutch. Definately get the wideband on there and check it also, but if that's good to go, your transmission probably isn't.

 

I'm not too worried about the trans it is a performabuilt and has less than 2 k on it. But I have broken 2 performabuilt already so I guess its possible.tu

 

any other ideas?

 

is it a triple disk converter? have you logged tcc slip?

 

New wastegate fixed it. Thanks for the helpu

 

Good deal! Too many times guys don't post up the fix.
