So I appreciate the dictionary meaning of the CARS do you have any tuning tips?

Last time I tuned an LT4 was in... umm... 2001 or 2002? Step 1 was to remove Hypertech tuning. After that I worked on reducing delivered fuel at WOT. That helped improve power level but I had a chassis dyno available so I could make changes in increments. The next step would have been looking at the WOT enable parameters to see if they seemed appropriate for the owner's style of driving. I seem to remember that I liked much of the LT4 tune as was and without having time to do some on-street driving I wasn't going to make too many changes.
Id love to get a genuine LT4 stock file. You know, for safe keeping of course.

Edit: After looking further into JET DST I realize i had it confused with a hypertech style programmer. I see now that it is a complete suite and looks fully capable. So disregard some of my post in regards to the JET DST. The OBD2 LT1/4 kind of got the short end of the stick when it came to tuning. It seems most people with LT1s tune on OBD1. The OBD1 LT1s continue to be disassembled, over the last few years there have been several new tables discovered and added to the xdf. Also people have continued to develop patches that allow for new functionality that was never originally there.

if you guys are talking about the LT4 and not the LT5 (ZR1), tuning the LT4 should be no different then tuning an LT1.
The one size fits all tuners i.e. JET DST, Hypertech, etc. are great if all you want to do is lower fan temps and disable CAGS or other simple on/off items. other than that they are absolute garbage compared to whats available. not to mention more expensive.
If your corvette is a '96, I would suggest looking at reverting it to OBD1 from OBD2.
There is amazing software available for the OBD1 LT1s. EEhack is completely free and blows most tuning software out of the water.
combine that with TunerPro, which is also free, and you now have complete tuning capability minus a dyno. the only equipment you'd need to purchase is an ALDL-to-USB cable from moates.com or other cable vendor.
