Did u replace those injector ?

[Collin Smith]

yes. its runs alot better. So quick question if i have shifting problems can I accurately tune my MAF? or anything for that matter.

[tana99ss]

I understand you want to get from point to point b but youre jumping all over the place tbh. would you say the shifting problems are tune related or bad trans

the transmission is usually the last thing that i touch. I try to get MAF dialed in ( easiest) , VE , Spark table, Idle , Trans.

I do think its tune related, it's always on the rev. limiter. So, what I'm asking is if I attempt MAF tuning will it populate accurate data to put on my MAF curve right? Pretty much I can't tune for anything with my trans messed up? is what im asking. Tune related for not.

You should take it slow, if your just starting to tune it, i would first tune up to like 4k rpm .... me personally i wouldn't be attempting anything near "rev limit". slowly tune your maf.

if your trans is jacked up no point in tuning it.
