I think it might be a good idea.

 

Set your commanded AFR to 14.68 and it will use short term trims to keep the part throttle AFR in check. Could even throw a little lean cruze in there if you wanted. I've messed with it and really didn't find any significant gains. 15.5 seemed about the best, any more and I'd loose enough power from it that MPG got worse.

 

i cruise around 14.9-15.0 high 30 timing and get 20-21mpg cruising. mye idc is 5% with a 60psi base and i run no narrowbands

 

 

yeah i got the narrow bands hooked up, and running semi closed loop with a little lean cruise plugged in... Trims are not that bad at all. I will see how it goes.

 

What gears do you have?

 

3.42s. that was with a 60e. i just swapped to an 80e so its a slightly higher rpm. dd trim is 29" tire also

 

yeah i have 4.10s swapping to 3.42s in a few weeks.

 

im very pleased with drivability of the 3.42s. put in the 80e last week with a stock converter so its a big *** turd. im still anxious to feel the new ratios haha

 

I love my 80. Do yourself a favor and get the pro yank multi disk 3200. I drove mine several months NA and it was great. Even better with boost!
