I just installed a MS3/5.3 heads combo on a 99z. Just for ***** and giggles we ran this car against another (01z) car before tune and could barely beat it the mods on each car are>

01 Camaro-
TH400
MS3 cam
stock heads
pacestters and true duals
stock lid and filter
Stock gearing for M6- 3.42?
Tsp mail order tune

99 camaro
MS3-5.3 stage 2 prc heads
tsp 1 7/8 headers- Tsp true duals
Underdrive pulley
K&N intake
M6

I really thought the head/cam car would smoke the cam only car
My question is how much do you think I will gain from a tune?

well im sure the cam only car has a stall since its an a3... and if you went from a dig, with you being an m6.. im sure thats why..

from a roll, you should have beat him i believe...

a buddy of mine had
f13 cam
5.3 2.5 heads same heads you have
373s
ls6 intake
3500 stall
full bolt ons
lid
mac mids

i had
ms4
410s
stock 98 heads
LT's
lid
ported 9090
full bolt ons


from a 40 roll because of his throttle and mid range with the 5.3s his nose would jump in front of mine and would hold it till about 110.. and we would **** down..


big thing is if you went from a dig or roll.. that will explain a lot

from a dig, i beat him by 2 tenths of a second and out trapped by 1 mph..

almost forgot.... if you are on a mail order tune, i would guess probably about 15rwhp min.

you also has to think you have an ls1 intake and he has an ls6... unless you didnt list all of the mods, like you left out his stall..

Ya he has a vig 3400 and we did both- roll from 40-50 and a dig multiple times. Ya the 99 does have ls1 intake and stock injectors.
