I would highly recommend Intended Acceleration; they are the most popular V8 (3.6 and 4.2) chip tuner in the US. I am running the IA chip in my car and am very pleased.

I was not very impressed with TAP's (www.tap1.com, 3.6 only) response when I sent them an email inquiry; they also have 0 positive and 1 negative performance feedbacks on the V8@audifans.com list. Numerous IA raves and no IA rants however. They are the only 2 V8 chip tuners in the US that I am aware of.

Contact Alex at http://www.intendedacceleration.com and tell him Jeremy sent ya
