I am experiencing EXTREME problems with my turbo, I am only getting 2-3 psi and in fifth gear after about 2-3 psi I acutally LOSE RPMS with the gas floored...what the hell is going on???

I noticed a small exhaust leak in the engine comparment that could be a part of the foul culprit...could it be my ECU is getting false reading? Could it be my secondary injectors have ceased to function? AHHHHHHH this sucks, it was running great 5 days ago, almost perfectly, 7-8psi no problem, and now...something is messed up.

I am brining in my car on Wednesday to a mechanic here that I trust and know. I am having him change the fuel filter, O2 sensor, but I don't know what else to try. What should i get him to look for (he probably knows, but I want my car running good before I pack it into the garage for winter.

 

Well if have an exhuast leak, fix that too. The other thing is to check the hose that goes to the map sensor, it is common for it to blow off and it makes the car run like crap.
