I cannot get my low trim to stabalize at all since my MAF translator install. No matter what I adjust the translator to, with the car at idle, the low trim runs from 81 to 139 and back again. Could the MAF be going bad?

Alright, I'm an idiot..the .00 reading was caused by the base setting being set for 580 injectors!!! So that's why it was getting the so lean reading at idle. That would probably also be the reason it wasn't hitting fuel cut, due to adjusting (reducing air HZ)for 580's.

Funny thing is it loved that setting,pulled hard, no fuel cut, less than 3 counts of knock and .8 O2 at 14 psi of boost.

So I went back and re-evaluated my settings. Since I'm running a base pressure of 44psi, it should make the stock 450's act like 490's. So I set the base settings for 490's started tuning from there again. I'm having a bitch of a time getting the trims to the rich side and reducing the base setting to a lower injector size just gets me into fuel cut quicker.

So for those with more MAFT experience: At the dragstrip has anyone jacked the injector base setting up to stay out of fuel cut. I figure with some race gas in the tank, as long as it's not knocking it should be fine right?

If none of this make sence, I'm sorry, I've been messing with this thing all week and my brain is shot. I'm about to rip in all out and go back to the stock setup for tomorrow!
