Reprogram For 1.6 Roller Rockers?
Ok, I've got a '95 LT-1 with Corsa exhaust, and X-pipe after the Corsa resonator, K&N Filter on the intake, and I just installed GMPP 1.6 Roller Rockers with LT-4 Spring/Retainers. The car is working fine, nice gain from the Rockers, although it seems to soot up the tail pipes a little more than it use to.
Question: Is there more to gain by tuning the PCM? I'm thinking there may be but I'm looking for an experienced opinion based on my minor mods.
Can Alvin and the other Mail Order tuners come up with a flash image for me from TTS DataMaster logs or do I need to get it on a chassis dyno?
TIA

I had PCMFORLESS send me a tune file that I loaded on with my lap top and cable I bought. The file was $75 and the cable was $80. I did notice a difference with their tune over the hypertech I was using. I'm sure it is better to get it tuned on a dyno though. When I get around to getting to the track I'll do some logging with TTS and send the log to them to see if any adjustments need to be made. Any advice on the rr's I'm looking at doing those next.
