MAST mass air translator user please chime in

seeking advice for my mildly modded 99 Pontica trans am LS1 cam, LTs, FAST intake.
My WOT air/fuel ratio is 11.5 and is pulling 2 degrees of timing (from 28 degrees at WOT).only Scanned w/ HP tuners.(I don't have access for any HP tuning changes)

considering a older MAST & a LC1 wideband to get more correct base settings to correct this (if possiable). to aviod the purchase of HP tuners which is costly am I'm not a tuner.



A link to a user manuel would be a great start.

Thanks

The LC1 is about 225-$250 and with it and the MAFT you can adjust your WOT AFR.

For $125 + S/H you can mail in your PCM and dyno sheet (or just the info you posted above) and I can get it adjusted. You won't need that much timing with the FAST intake up top either. I'd guess that's why you're losing timing; knock retard. For $225 + S/H I can just ship you a tuned, certaified, remanufactured PCM to avoid any down time. Let me know if I can help.

seans to me the smart thing to do is have you adjust the base tune on the PCM I allready have.

?1.do you cammand the desired air/fuel ratio at all RPMs? and when it's corrected will it
ilimitate the PCM from pulling timing?

?2.what is the desired WOT timing (w/ FAST78) I'm thinking if timing is taken out it mite
feel like less power?

?3.do you tune the MAF?

I plan to be in the Fairfax, VA 22030 area in the near future if I bring you the PCM w/
an appointment can I wait an observe while you do you're adjustments, and maybe learn a little
about tuning.

Thanks
