yes, shoot for a negative average. it seems like the more things you change the harder it is to keep your ltrims in a tight range, you can mess with your maf table but i choose just to let the ltrims do the work for me. with these injectors if you can get them in the -10 to +5 range thru the ltrim cells and 0 at WOT i would be happy.

right now i am running leaded fuel and no 02's at all. no 02's means no ltrims, no ltrims means you have to work on the maf table. it works suprizingly well but the 02's with ltrims work better.

 

i'll be running o2's thats for sure. i want it daily driven with out a hitch.
