300.66 rwhp / 318.45 rwtq

 

mods in new sig.

 

Looks good, I am still hunting the elusive 300+ RWHP. Mine dyno's out to 291.5 with similar set up. Most of the 05's + have a base line of 259 to 275 RWHP with no mods. Guess mine was a 259 to start with. It sucks to loose 15 hp out of the box. I was using the DTP tune on my xcal. I was not able at the time to use doug's tune. I feel really confident that I might be closer to 295 RWHP with his tunes. I am hoping that the 4.10's will take up some of the slack. My torque was 299 with the DTP tune.

I noticed that when I was driving home, at WOT above 80 mph, I had detonation when in 4th gear. THIS was not Dougs tune though.
