My first guess is that he has the wrong "calibration" on the MAF meter... like the injectors are too big or too small.
I've seen several foxbodies with S-trim (V1) vortechs run pretty darn well with 42# injectors and an appropriately "calibrated" MAF meter for 42# injectors. That's a great start, and then fine-tune with Quarterhorse or Tweecer.

So are those two programmers able to work with any 5.0 motor? I use LT1-edit on my car but once you mate it with your computer you can't use it on another lt1 car unless you buy extra licenses. (at least that's the way it was years ago, I haven't f'd with tuning in years). |

Anything available for a 5.0 car is going to be a piggy back, meaning it has to stay attached to the EEC at all times.
I agree with coupe, more than likely it is a improperly calibrated MAF. Need to check for any vacuum leaks as well. Any air entering the engine after the MAF can wreak havoc on getting one to run well

yeah I'm Luke's bud.
I found out he has 30lb injectors and he said the maf has 30lb on it somewhere too. He also said the heads were edelbrock performers. Still tryin to get info on the cam, but we think it's a b303 or smaller. It doesn't idle very aggressive. The car ran fine before and now it's acting up. |
