cobra vs gt mass air

[95stangGT]

With my turbo kit I received a Pro-M mass air calibrated for 42 lb injectors but for a cobra computer. Now I have 42 lb injectors but a GT computer. What kind of problems would I see with this? I already fired it up and it idles perfect. Just wondering if it be a must thing to do before getting the car on the road. Thanks

i dont think youll find any problems at all. i know whenever us guys use the Tweecer, we use the cobra's computer code. our cars seem to just like the cobras comp. inside every GT is a serpent waiting to be unleashed

It's going to run fat.

I made the same mistake myself by using the Cobra computer, and 24 lb/hr injectors with a MAF calibrated for GT 24's or Cobra 30's.

What about installing a AFPR to lower the fuel pressure then?

Won't matter.

Because the Cobra calibration makes up for "one-size-bigger" injectors, you're basically telling the car to act like it has 42 lb/hr injectors, but to use 36's instead. For those 36's to act like 42's, they've got to dump more fuel.

The only way to fix this besides buying the correct mass air meter is to alter the MAF curve with some kind of self tuner.
