First of all, a huge thanks to Joe Donovan at Performance by Joe in St. Louis MO, not only is he a great tuner, he is a great friend. He is never satisfied, and I finally had to tell him to stop so we can go grab some food and brews! We had problems eliminating the lean spot that the SRT's have for the first 1.5 seconds or so on the N/A pulls. The VEC3 is supposed to eliminate this according to Sean@Roe, so Im sending mine in for an upgrade. Peak #'s didnt change a whole lot on the N/A tune, but from 3500-4500 there are big increases, 25+HP in spots and even more torque. This is tuned without N20 (before and after Belangers, and then tuned):
This is the 125 hit (100 wet and 25 dry):
and the 175 hit (150 wet and 25 dry):
And both:
571/684 on a 125 and 606/762 on the 175, I was VERY pleased! It made the advertised HP#'s under the curve on both hits as well. I forgot my jets to dial in the 175 on A/F (a little lean), but im going to tune on the street with my AEM to get it finalized. The 125 shot couldnt be any better on A/F IMO.
Trucks mods are:
PBJ Tune
VEC2
Belangers
Custom JMB dual 3" exhaust
JMB CAI/CC
Custom NX by JMB and PBJ
