2) PCM - I don't know how much opportunity there is here, but we'll start working on this one next week, and we should have PCM'* available by the end of June.

3)

4)

5)

OK, let'* hear everyone'* best ideas, so we can start working on this...

Any luck yet??

Research and Development takes a long time. I'm sure they are in the process of something right now.

Last Saturday I bought a K&N drop in air filter for my GXP. I haven't had a chance to drive it yet, it'* my wife'* car. So, I don't know if there is any SOTP difference. I also plan to gut the air box to improve air flow. Hopefully these 2 changes will add a few h.p. I'll let you know if I can tell any difference SOTP. My GXP only has 200 miles on it, so the engine is still tight.

If there were ten steps to this process I could say we are two steps away from completion.

I wouldn't send you a dime unless your wife was starving. You've screwed so many members on this site out of hard earned money, you should be embarassed to post here. Push me a little harder (or let me find some spare time away from work) and I'll pursue you all over the internet on other automotive forums.

Bashing Scott Cook only makes him look better, considering your reputation.

All the good things having been said already, let'* get back on topic. Of course I'll retract my comments when I hear about my transmission being shipped.

Will, you ordered a transmission from that bozo a year ago and havent gotten it? Omfg, good thing i never ordered the 4.0L chip. I almost clicked Submit Order, but stopped after i saw a couple posts that he charged someones credit card for a bulletproofed 4T60-E and a year later has still not shipped it.

Honestly, I would have sued the guy by now. I dont know what your waiting for. DId he charge your credit card?
