Well, I think I fixed the fitting but now I can see some of the welds on the exhaust pieces are leaking so that is my next step.

I'm pretty excited because I believe my "open loop on command" trick worked. I did some logs and the AF correction went to 0 when the relative pressure went above 0 psi!!

I'll try to give a quick rundown for those who don't know. The theory is that the MAP based cars have trouble with the ECU wanting to learn around the eManage tune if you don't ONLY tune in open loop. But with these cars, they don't go into open loop right when boost starts. This means there can be times where you are in low boost, low throttle and the car is still in closed loop which means that any tuning done to that area will eventually be learned around by the ECU.

After lots of research, here is what I came up with (last post): http://www.rs25.com/forums/f72/t1912...l-emanage.html

Basically tricking the ECU by sending a fake TPS signal whenever the relative pressure goes above 0 psi.
