Dyno Tune advice
Going to dyno tune 2 Vettes, 1 96 and 1 93. For the 93 I am going to use TTD datamaster and use a Wideband. Should I go ahead and get a chip burner so I can burn chips right after my tuner sends data,or just do a dyno then have the tuner send a chip , then dyno again etc etc.
The 96 will probably do one run, then be happy with a fan and little bit of timing change as it is supercharged.

I guess it just depends on how fast you want results. The best thing to do would be to get a chip burner and TunerCAT and do it yourself while you're there. The software is reasonably priced.

I have no idea how to tune a chip, that is why I rely on you guys, tuners. Is there a good tutorial? Tuner Cat?
I need it tuned pretty quickly, but I can wait if the cost vs gain isnt reasonable. I make 400rwhp/428 tq with his tune. It is just we radjusted the tune because the A/F ratio was 12.4 to 1, butI had to lower the fuel pressure to 36psi, as low as the regulator would allow. SO he adjusted it so I could use 42-45 psi, thereore getting the injectors to spray better, and I wanted to check it and be able to adjust it becassue he tuned it, very well driveability etc etc, but wanted to fine tune it. I originally used DIACOM data(on the street driving around WOT, cold, etc )(and Wideband on the DYno, and I know TTS datamaster is better, and with the Wideband on the DYno again with this software, I am looking at refineing it.

Steve,
If i were you I would get hold of Tjwong (for the 1993)...he did my 92-383. It was originally a tune by Ed Wright but I needed an update and Tjwong got it right first try..plus he is honest and reliable, that's hard to beat...

I thank you for the advice. My tuner is very good, I am just trying to fine tune it with Datamaster and wideband on a dyno and while driving.
