I have a problem, my car has lost some bottom end power and I dont know what it is but I know its one of 2 things. It could be because I took mt Throttle Position sensor off and put it back on without setting it to .99 volts Or it could be that my MAF is too big, I have a Prm M 75mm and my motor mods are- 306 w/ E303 cam, 65mm tb, gt40 intake, #24 injectors, MSD, Longtubes w/ offroad H and flowmasters, I am buying Edelbrock Performer heads later this week so that should even it out if its too big, please help because this has me concerned. Should I sell it and buy a smaller MAF, I got the Maf for $80 so I couldnt turn it down. It has gained power in mid-range and top end. Please Help me guys!!! [&:]

This the same motor as before?? But if you havent put the TPS back to .98 then it can cause some running issues like i have learned last few weeks. Try putting the old MAF back on.. and reset the puter.

The mass air isn't to big for your combo. Is this Mass air calibrated for the 24# injectors?

Dan89lx

its calibrated for #24's. I havent unplugged the battery to reset the computer yet and I also havent set the TPS yet. Im relieved to hear you say its not too big.

So you left the battery connected whne you did the install? I always disconnect the battery before undoing wiring. On the top of the mass air does it say 24's N/A? In other words it didn't come off a supercharged car?

Dan89lx

I know it was stupid but I was in such a hurry I didn't think about unplugging the battery, I normally do but it just slipped my mind. It came off of a NA car.

sup95cobra

another ? did you clean it?

Dan89lx

yes its clean as a pin

Dan89lx

is it likely that I would notice a decrease in low end power, less than 2000 rpms with the bigger meter. Is my throttle body too small? I have a 70mm tb but I have to get it welded before I can put it back on.

sup95cobra

Yeah I would get that 70mm TB on there
