My tuner is tuning my car right now and is telling me its only gonna make 450whp. Needless to say I am hoping for more. Anyone want to put in your $.02 on what it should make?

99 SS M6
Forged 370 11.5:1
TEA/TFS 225's yellaterra ultralights
239/252 624/595 111+4 Tooley spec'd cam
Fast 102/102
TSP 100mm MAF, FTP 104mm lid
TSP 1 7/8" LT's
3" true duals dumped with Kooks race mufflers no cats
10 bolt 3.42's

 

My 11.5cr 347 with TFS 215's and 240/244 598/604 112+4 cam, Vengeance ported Fast102/102, FTP 98mm life with TSP 1-7/8 headers and TSP tru duals through a 10-bolt with 3.42's put down 466/416 on a realistic dyno tune speed density, M6 as well. Dynojets dyno a little higher than some of the others out there.

You will have a very strong running car, no matter what the ego roller says.

 

Got my car back today. I was asking the tuner why the power was so low and he is saying that the cam is hurting my power. He also is saying the fast 102 intake is hurting the power. He is telling me that a bone stock LS2 intake makes better power than the 102mm fast intake. Oh ya he also ripped 2nd gear out of my car while he had it for a week tuning it lol. What do y'all think?

 

I think your tuner is a ******* idiot, and you should find someone new.

 

i would like to hear Tooleys idea behind the cam specs.

 

This. Now.


Ls2 intake doesn't even make as much power as an ls6 intake.

 

Wow.....Find a new tuner ASAP!

 

Pat-G is in TX. not sure how far he is from you. might want to look into if he can tune your car.

 

FWIW: 370 in sig-

11.9:1
stock l92/ls3 top end
5000!! converter
373s
28" drag radials
1 3/4 headers
sd tune
231/236 .615 111 cam

Put down 437Rw on a dyno that is known to show around 12Rwhp low.
That was with only 60 miles on the build.

I swapped to a 3500 converter and with 1500 miles for the retune on that dyno I was expecting roughly 45XRwhp..

 

Just thought I would update for anyone that was following this thread. Ended up getting ahold of Sam Miller for a retune. Very happy with his work. He got 500.13whp and 457tq. Gonna change the plugs and take it back to him next week for a follow up. Very cool guy.

 

Congrats on the better numbers! I'm running a forged 370 with 11.5:1 compression as well, and love the power and torque this thing makes

 

So what did you do to go from 450 to 500? just a different tuner?

 

Lol... amazing aint it. Tune is everything. Absolutely nothing changed on the setup between tuners. Sam Miller brought out what the setup was really capable of. Big thanks to Sam and Speedtek.

 

Now go race it and get a 1/4 time for it.

 

God, that first guy you had tube it was an idiot. You should have turned and ran when he told you the LS2 intake was better than the FAST.

 

I would've figured it to make a bit more

 

Kind of ironic this thread coming back up cause I just found out my tune is totally jacked as well...causing my low dyno numbers! These 370 ' s don't have much initial luck on the dyno lol

 

The tuner really suggested that an LS2 intake would net more power than a FAST 102. I would have ran the other direction.

 

I don't understand how someone can even do a WOT tune that's that bad unless he was purposely tuning it to run in the low 11s air fuel and like 20* timing or something ridiculous
