Ive got a 99 z28 M6, So far Ive got longtubes, lid, catted-y, and loudmouth exhaust. My best time is a 13.6 @ 103 Does that seem slow for the mods I have? I see alot of people running that stock. But Im just curious. thanks

2.25-2.3 60 ft's. And shifting at 6k.

Actually your 60' is too high but still your MPH is damn low for what ya got buddy it should be somewhere between 107-109 atleast

Altitude & weather or even your clutch might be slipping abit ??

Im wondering myslef if my cltuch is slipping, this is my first manual car and really dont know what to look for unless its obvious, like hitting the gas with clutch engage and rpms jump up.

I agree that the 60 foot is killing your et but you should still have much more mph unless the clutch is not holding. Checking out your clutch is the first thing to look at, then some sticky tires should be on your list. Tuning may also unlock some power since you've installed a good amount of aftermarket exhaust stuff.

when I was stock on street tires i would run 13.4-13.5 with a 2.1-2.3 60` and an average of 107-110mph.

and with same mods as yours I did 12.6 , look at my sign. except I got spec3 on the 12s run and no ls6 intake.
