I am down in south florida (delray beach to be exact) I work for Diablosport and do custom tuning for customers on the side. I can do a lot of the older GM stuff that not many people do anymore, i can do lt1 as well. I also do ls1, ls2 etc etc if you have a predator/trinity. If anyone needs help/custom tuning or questions at all, hit me up @ donc@diablosport.com...i would be more then happy to give anyone who needs it a hand, either learning to do it themselves or me doing the dyno tuning for them. I'm not really trying to advertise myself, i just know what a pain in the *** it is to find anyone doing custom tuning on these cars anymore.
