Got back from the dyno this week. My local tuner wanted to do a few more tweaks and spend a good deal of time with the car fine tuning many of the transmission parameters. Below are the results from the baseline.

He wants me to head back in cooler weather to throw it on the dyno and see what the gains are since the temps were in the mid-90's. The cars temps suffered from heat soak and required a lot of cool down time between runs. The baseline was done back at a dyno day in much cooler temps. To top it off, I was getting nearly 29mpg on the highway cruising between 55-65mph on the 45 min drive home.

All numbers are SAE....and man does it feel good.

314.57 rwhp
334.26 rwhp

For dyno number reference, check out the latest issue of GMHTP with their GTO project. The 06 GTO project car with an intake, predator tune, UD pulley and new MAF meter put down 338.2hp & 324.1rwtq through an auto on this same dyno. It took a full exhaust including long tube headers, high flow cats and a catback to beat the G8's tq numbers.

Can't wait to hit the strip!
