Here's the deal, Had my car on a dyno jet a couple of months back and from what i'm reading my torque and HP should be close to the same.. I know I should get it dyno'd on a Mustang but... 349WRHP / 308RWTQ This make sense anyone? That's also tuned for 87 oct. Ideas??? maybe the fuel??

I would say the 87 octane has an impact paul. The new G8 has the LS2 but runs on 87 octane which is why it comes with 361hp stock

+1 could be the fuel, the hp is normal ,but a stock 05-06 goat's Torque should be around 325-345 give or take a little depending on tranny A4's dyno a little lower.

and the g8 does not have the ls2, its a 6.0 litre ,but its the L76

Really? its the L76? I did not know that, learned something today

GOAT06

Whats the difference between the LS2 and the L76 besides the intake and heads? anything? Is it the same block?

06brazengto

from what i read it is the same block as the Ls2 with the L92 cylinder heads and a L76 intake.
and the compression is lower 10.4.1 vs 10.9.1 ls2

Why would you get a tune with/for 87 octane? I am gonna say the tuner would have to pull timing to use regular.

i believe the l76 is more comparable to the ls3 as they share heads too.
