Hey guys, can you give this current tune file a look over and critique. i had the car out the other day doing some maf tuning and i thought things were pretty decent. i started it up today after sitting a few days and idle is very very lean. lean when i rev it.
i was working on a ve sd tune the other week, but im not sure if i didnt have the maf failed correctly or if i wasnt doing something correct, but i had to take a lot out of the vve table to the point the numbers are close to gen3 numbers, and i dont think thats correct. so i threw in the towel and started to just do maf instead lol.
car was tuned prior to the ported heads and intake by a shop and the tune was good, i decide to tune it this time around after porting the heads and intake,im just to the point of being frustrated with it.

71 chevelle, t56, E38 ecu

i will also attach the sd tune just so you can see.
