i think jet can burn chips for you, you just have to give them all the specs. check with summit

IMO the "pre-made" chips are not worth the cost. Get one burned for your motor, you've got enough mods to make it worthwhile more than likely...all the car chips I've seen do almost nothing, *maybe* a 1/10th in the 1/4 mile, which isn't much when you are starting with a 16 second car. I only use the car/ 1/4 mile comparison because its measurable, and they "chips" have been pretty consistently found to do almost nothing. I believe all most or all of them do is slightly change the timing and perhaps A/F at some throttle positions. Obviously not enough to make much of a difference.

www.fastchips.com (Ed Wright) burns custom chips based on your combo - another good option is to get into burning them yourself............ www.thirdgen.org has a PROM burning forum that has incredible amounts of helpful info and people. Costs about $250ish to get into it............then you can tweak and tune any parameter you want. This is what I'm doing when I get around to it.
