So you are still using a stock MAF?

To answer your question, if you truly are pegging the MAF at 5k rpm then changing the injectors will not help you. The MAF will still max out with 30's at the same rpm. Only a MAF change will fix that. Changing the MAF curve in the EEC will not fix it either.

With that being said............

With the mods you have listed, you should not need injectors yet. Actually I am surprised you are maxing out the MAF. BUT I am sure you could benefit from an aftermarket MAF
