Hey...

I recently installed a 270 amp mechman alternator onto and i am having some issues. While parked everything is fine but when i put the car into gear reverse/drive it drops to a lower rough idle, than my voltage drops significantly (down into the mid 12's).It even hesitates sometimes when I heat the gas. . Mechman said raising the idle of the car would resolve this issue since it isn't spinning the alternator fast enough to maintain volatage but i would need a tuner. I understand that the voltage output of the alt. is pcm controlled and i would need an external voltage regulator to ever reach higher voltage then what the pcm sets. But the idle is controlled by the pcm as well and EVERY shop i call tell me they are incapable of raising the idle..am i asking the wrong questions?

Please help.

I didn't find the right solution from the Internet.
