I'm running a 302, stock bottom end, trickflow twisted wedge 170cc heads, cam with 525 lift, 1.6 ratio rockers, edelbrock performer rpm II Intake manifold and plenum w/ plenum spacer and a 70mm throttle body. I already got 36lbs injectors. Will I be fine with that large of injectors?

 

It's over kill but should work. IMO get a tune even if you are running a calibrated MAF.The larger the injector the MAF is calibrated for, the worse everything gets since the error in the Load calculation gets bigger and bigger. I can get real technical on the subject but a tune would be the way to go. what you running for a maf and fuel pump.

 

A MAF sensor calibrated for 36lbs injectors and fender fed cold air intake which I also have. So the MAF sensor is a perfect match for what it's calibrated for. And a walbro 190lph in tank fuel pump

 

You can run the calibrated maf if you want but if run into issues get a tune ( some get drivability issues some don't) Like I stated the larger the injector the MAF is calibrated for, the worse everything gets since the error in the Load calculation gets bigger and bigger. A "calibrated" maf is only tricking the ecm, you are at the mercy of teh calibration, a tune recalibrates the ecm..ends all of the guess work.

 

Are you local to Marysville WA? Know of any places that can tune a stock ecu? I know the guys at Marysville Speed, Passing Lane Performance and Maxwells but they all said they will only tune an aftermarket ecu

 

you seem like you know what your doin ... i got a 1990 foxbody and was wondering if I could talk transmission with ya ?
