I have come to the conclusion that tuning is really a lot more simple than we make it to be with today's modern chips. Gorilla tuning will get you 99% of what days and days of fine tuning will bring you
1) if you can leave at 10-12 psi of boost, or better, without undue spooling delay on the line, then your converter is close on stall. I suspect the rpm will flash well into the 3000's and probably closer to 4000. Upon launch, it should flash to about the same rpm as it drops back to on the shift to second and third. Modern converters seem to be able to do this and still feel responsive in normal daily driving. I hate that "give it some gas and wait for the car to start moving" feeling.
2)Don't try to run the max timing in low gear that you can get without KR. Run enough so that the car will spool easily. Eric's chips are often too rich on the default so pull as much as required to get the revs to come up easily along with the timing. You don't want to heat the chamber in first and second more than you need to in order to get the car to launch. Any more just increases the likelihood of KR in third gear where the increased load on the engine and high chamber temps don't go together.
3) Don't worry about third gear timing. 18 degs will probably work as well as anything.
4) Stay in the power-band of the engine. Don't try to push the upper rpm limit. It's a turbo car. Boost is king and anything else is a pawn. Yes, I know the difference between flow and boost but we are only working with one turbo and one engine combo at a time. Just try to stay within the efficiency window for your turbo. If you increase boost and the intake temps take a steep jump, go back down.
5) learn to drive the car that you have...find out what works with it, not some one elses in other words.
6) The more alky you spray, the harder it is to optimize the launch, but, the safer the engine is on top end. Also, the more alky you spray, the less sensitive the tuning will become for A/F ratio.
Speaking of A/F's, I suspect that low gear should be around 11-1 and third gear should be around 10.8-1. Getting too rich will kill acceleration, getting too lean can cause strange noises. I suspect the fast alky cars are running egts around 1650 at the big end.
Your slic is fine. Watch who is running what at the nationals this year in the alky class. Slic's are easier to tune and more responsive on the street.
Quick street cars are a helluva lot more fun than real race cars unless you are just an old fashioned masochist at heart.
