99z28 Mac mids, ory, catback and K&N fipk results Went ahead and had my car dyno'd/tuned on Saturday. Glad I did. The car was running extremely lean, couldn't even make a full pull on the first two runs. Had to keep dumping fuel to it. Major props to Mark from Ztuning/Tach it up, for hooking me up. He did a great job and got the car where it needed to be. We made 6 or 7 pulls and this is what we ended up with:
345hp/352tq --- Pretty good numbers, more than I expected...mods done to the car are in my sig.
Thanks again Mark...You tha Man!

Not yet, I guess the car was running 13.4's with 2.1 60's before. The car did pick up some hp from the new tune. So I would guess I could be seeing some 12's if I get some stickier tires. I think a converter is in the near future as well.

Good #'s.Hey you want some advice about those mac headers? I had the same headers and if you cut the collectors off where the diameter starts to get smaller and put 3" tubing from it to 33" long on my set up or probably around where your exhaust Y's you will find alot more torque in the midrange. i gained over 2/10ths in the 1/8th mile. Also if you don't already have it replace the y with one of the flowmaster y collectors from Summit/jegs ect. Cheap upgrade and really made a big difference. Just my .02.

Nice. I always like the Mac's. On my Firehawk I switched from Mac's to Hooker LT's and the car didn't feel as strong driving around town. I figure I gave up some midrange, but the driveability on the Mac's is great.
