Car is running a little rich and needs a tune. I just want a street tune for daily driving or whatever is necessary to have it running properly. Is it possible to be tuned w/ this setup w/o dyno time? I'm trying to be a little cheap because I don't have $400+ for a dyno tune. Kind of new to this so info would help to get me in the right direction.

Del Sol w/ the following. Any suggestions?

b16a2 block,
GS-R Head
P72 ECU w/ two step
AEM SRI
Stage 2 Skunk 2 cams
DC Headers.
