Re: Went to the dyno--really lean, help
If the fuel pump isn't keeping up at higher rpm's, then it would be the problem. I have a new pump and should have it and a fpr installed by Saturday. Maybe Dyno on Sun or Early next week. We'll see then.

Re: Went to the dyno--really lean, help
A failing fuel pump could be part of the problem. The more parts you throw on a speed density stang the leaner it is going to run until you bump up the fuel pressure.

Re: Went to the dyno--really lean, help
Well I have also heard that maybe the computer is part of the problem, too. Something about different fuel curves and not being compatible with parts--86 only?
I'm gonna check my computer number today.

Re: Went to the dyno--really lean, help
86-88 speed density ecu's are the same.

VM1??????
I have heard they are all DA1 from a reputable source but you may be correct.

Re: Went to the dyno--really lean, help
Well, I looked at the computer today. Unless I'm stupid (could be due to my physical therapy school demands), that is exactly what it is.
So, I guess we will see how things go. I am putting the fuel pump in tomorrow and should have the reg on sat or sun. Dyno next week.
