Not the same scenario as tuning a 2nd Gen Neon. You have the option of getting a Stage 1, 2, 3 with parts produced by Mopar. We could not even get a full Stage 1 kit for the LX's. Some parts were never made and I just found out 2 months ago they discontinued making the LT headers for the kit.
The economic downturn has really stalled Mopar's interest and enthusiasm for making performance parts. You know that if Mopar is not producing them they are not readily sharing info with the aftermarket to let somebody else produce what they won't make.
Tuners are learning by trial and error and from other people's mistakes. Some have been doing this for years and have a baseline for what can and can not be done safely. The introduction of the DiabloSport Predator really opened up the possibilities from performance parts for these cars because now anybody was able to get into the computer and tune. Problem with that is there are no boundaries to the system and you can turn off/on/up/down stuff that you shouldn't and quickly make the engine go BOOM.
In the past 1.5yrs I have seen superchargers, turbos, twin-turbos, and twin-superchargers enter the market. Nobody knows how long they will last or how long the engine will last with them installed. Not many are willing to put a warranty behind their product so its scary. I'll let others that can afford to replace a $8,000-$10,000 engine without blinking be the pioneers, somebody has got to do it.
