The MAF and computer are working together thinking you're running 19 lb injectors. You cannot simply upgrade injectors and not the maf and or get a tune. The MAF is the easiest to do. Get yourself a MAF calibrated for 24# injectors.

I believe, and I could be wrong, the cobra PCM was flashed for the 24# injectors. If I am wrong, then yes the MAF will be sufficient.
