I feel I have to jump in here. I beta tested for a very well known tuner for 1 year before a kit was released on my Lexus IS300 I had. For the record, beta testing is NOT for everyone. Let me tell you what my car went through.
My car went to the shop for 8 weeks for the kit to be installed. 8 weeks! I started on HKS FCON ecu, Garrett turbo, Spearco FMIC, 550 cc injectors, fpr, fuel pump, MSD ignition, etc. Unfortunately the IS300 ecu learns and piggybacking that car is almost impossible. The car jerked and shook violently under partial throttle. The car would try to return the A/F to stock levels (14.7:1) and when it couldn't it would start toying with timing. Ultimately it started to misfire, then consecutive misfires, then limp mode and the car running NASTY rich. Unlike this car, I could not turn the car on and off to reset the LIMP. I had to unhook the battery cable for about 1 minute. So, I was unhooking the battery cable every other day in a business suit! Sometimes it was pouring rain and I am opening my hood unhooking cables. Talk about embarrassing. This went on for nearly 4 months!
So back the car goes to the shop, keep in mind it is 6 hours away. At this point we go over to full standalone, 720 cc injectors, Dual feed large fuel rail, lower compression, consider different boost controller, plugs, etc. This time my car is gone for about 7 weeks. Well, once we went over to Motec, the car ran quite well.
Long story short, is I had to buy a second car and my car was gone for about 4 months in the first 6 months after I bought it. Was it a headache? Yes. Was I a beta tester? Yes. Should I have expected there to be problems? YES! If you guys want to test something you must understand what you are getting into. It is not a full release for a reason.
