Wanted/LF Tuner in MA/RI/CT

8

88FieroGTS

New member
I'm in serious need of my car tuned...
Mileage is s****y.
12MPG in a setup most are achieving 25-30+

It's an '88 Fiero, with an L67 (1999 Trans, ECU, Motor)

Having some horrible Negative LTFT, not sure whats causing it at all.
Any help is appreciated.
 


Getting up to the 14 mark. I've looked in a lot of places for leaks, can't come up with one.
Nobody local has a smoke tester until Monday unfortunately.
 


No problem. Seems like this issue is elusive to everyone.
I do notice Im at 11"hg at idle according to my MAP. Have a new one coming anyhow.

Do hear a slight leak, can't pin point it.
