Default how much of a loss?

hey guys. i have a 99 ss m6 and mods in sig. now im still untuned and i was just wondering if it really makes that much difference in tuning. i truthfully dont feel any difference from stock as i do now, but maybe its just me.

well..for one..13.6??? you gota learn how to drive..LOL
I did 12.7 bone stock...LOL

with just what you have you should be able to get into the mid to low 12's with ok driving and some semi sticky tires
400 hp guys are in the mid 11's easy...
350 hp guys(basically where you should be at after a tune) should see 12.0-12.5 with a good driver and a good set of tires

plus it will be so much funner to drive with a tune.it will wake up teh cars throttle response so much

yea i definetly need to learn how to launch the car. my tires suck at the track though. i was loosing traction in 3rd gear!! i know i dont have that much power to the ground either. the tires are practically brand new and i only had 19psi in them when i went to the track. they are 285/40/17 BFG KDWS in the rear.

Don't mean to laugh, but the numbers in this thread are rather unrealistic if you ask me.

you kiddin' me??

I have a 98 f body here in kc with full bolt ons and a 220ish cam and heads running 11.3 with my tune.....
and he only put down 379hp locked on teh dyno...


good driver..good suspension...good tune...all teh #'s above are very possible...

you can expect 350-360 hp with headers and a lid and a good tune..
many 400hp cars tuned by me in this area...11.5-11.7
350 is definately good for 12.0 -12.5 easy

again..traction willing..LOL

Sounds like I need to come down there to make some passes...

On dr's, lt's, td's, ssra, lid, no air filter, stall, 3.73's and a tune on a cool day....I went 12.56 @ 109mph with a 1.71 60'. You guys have some special air down there or something? Running less weight, no sway bar, no serpentine belt?
