We went back to the track today for some more testing and the Mopar Challenge racing series. I got 9 runs in the R/T and beat my previous best on a couple of runs. My new best is a 13.188 with MBRP cat-back, Techco CAI and 85mm throttle body. I ran stock tires, stock psi, 87-octane, no tuning, etc. All stock except those 3 performance mods, plus a strut tower brace. More testing to follow ...
Thanks! It was a .558 with the stock TB. That sucker doesn't dyno high, but really has a nice throttle feel to it.
