Guys...Tom has been tuning my car and we thought we had it...the drives perfectly but runs lean on the dyno so I haven't been able to make a full pull yet.
It runs @ 13.5:1 (richest) on the dyno. Tom is gone now for a month and I need this thing done so I can sell it. He sent me a tune and it was supposed to be richer...I put it on the dyno again today...and the a/f was the same. I tried richening it 14% with my xcal...same...still lean.
Tom knows what he is doing...I just want to make sure there isn't anything more I can do.
It has delphi 42's, 80 mm Lightning MAF, and a Walbro 255lph high pressure pump made for a mustang. Several months ago before putting in my new turbo...it always ran rich, but not very well. I am at a standstill, and I am prepared to just sell it as is w/o ever gettings #'s after I have spent the last 2 yrs building it!!!!
Anyone have any suggestions?
