First Dyno (graph inside) - How can I lean the A/F? My 2002 Trans Am (non-WS6, M6) has 5600 miles on it and I decided to get it tested.
My mods (that matter on the dyno) so far are MTI Clear Lid, FRA, and TB Bypass.
My best run was 312 RWHP / 330 TQ
My worst run was 310 RWHP / 327 TQ
These numbers are SAE uncorrected. Temp was low 80s. moderate humidity.
The A/F Ratio was pegged a 11.x --waaaaay rich
How can I lean this out? The guy told me I have 15-20 RWHP just in the A/F mixture. Will descreening the MAF help? The A/F looked fine (from the little I can see) before WOT...so I don't want to screw that up. Perhaps PCM tuning or HPP? I don't know anything about computer tuning on our cars. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
I am happy with how consistant the runs were, and the car sounded great (super loud in the room
).

The guys at ATP were awesome - I highly recommend them and their prices are great.
