i installed my blower last august. it has worked great up until just before i put it away for the winter. i have a 95 and i upgraded the injectors to 30 pounds adjusted the fuel pressure got colder plugs and a 255 fuel pump.i do have a pro-m meter calibrated for the 30's too. other than that its stock. now my question is that lately it seems to be runnin really rich and stutterin when i drive it. i was told it could be becasue i dnt have a blow off valve im only runnin bout 6-7 lbs of boost. i hooked a scanner and it said i had a bad 02 sensore could that be why. i dont know im confused on why it would stutter like it does. thanks for any replies.

im not to familiar with emission constrolled vehicles.. but i think that is the effect of a bad O2 sensor. if it just started to happen that would be another clue also. have alot of miles on the car?

My reserach into my own setup has me believing a BOV is needed no matter the boost for a really safe tune, but if your car was doing OK until recently, it is surely something else.

Pull the codes. A faulty temp sensor will cause your symptoms, but unless you get the codes pulled it's only a guess.

I was wondering if he decided to run more than 6 psi, what id he ran 10-13 or somthing like that. Will that put to much strain on his engine?

I had never been able to run my 95 decently until I got a custom chip burnt for it. The computers are really a pain.

A bad O2 sensor could definitely cause tuning issues, and you should see your problem go away just by replacing it.
