Pontiac GTO 2004-2006 - 2004 GTO/M6 H/C/I numbers

I had modern muscle in Oswego tweak my tune after I swaped out my TR230 cam for an SNL V.2 cam (22X/23X .61X/.61X, unsure exact specs SNL does not give them out.) and was quite pleased with the results. I also have ported 243 heads, pacesetter LTs, an UDP, and a ported FAST92/90TB and some other supporting stuff I can't think of right now. 243 heads are lightly ported by a friend of mine, mostly to clean up casting flash and such. Let me know what you guys think. (p.s. modern muscle is a great shop, and really knows there stuff...big thumbs up!)

Not bad. With some PRC or AI CNC'd 243's you'll see much better numbers.
