Here is an old dyno video of my twin turbo 05 GTO.
Here is an old dyno video of my twin turbo 05 GTO. This was it's very first trip to the dyno after some initial street tuning. This was at 16-17 psi with a 2.5" exhaust on a MAF tune. The car has since put down 795/806 at ~19psi with a 3" exhaust and speed density tune- with the boost falling off on the dyno due to not having a load against it. If it would hold past peak torque, it *should* be in the 850 whp range or so. This is on pump gas with alky injection.
