I had 1 3/4" LG Super Pro Headers (no cats) installed and dyno tuned at Horsepower Sales yesterday. The car is a 2008 M6 with NPP. It had a Callaway Honker and a 160 stat installed prior to the baseline pull. Also installed MSD plug wires, NGK TR55 plugs, and a Royal Purple oil change at the same time as the header install and tune.
I gained 42 rwhp and 38 rwtq.
It runs great and sounds like a beast!
Thanks to Jeremy, Roger, and the crew at Horsepower Sales!
Um...am I reading it right that it says you made 461/464 with intake/exhaust/tune? I think we've just found one of the most generous dynos in the country
Thanks again for the business. The LG's made that thing sound killer
We have asked Mustang dyno a few times last year about the setup specs they put in when they first set it all up last year. They swear its fine so we just let it roll.
This is also why we always do the before and after pulls to see the real gains and then take her to the track

Whatever it is the gains are as to be expected for that setup.
Hmm, 40 HP increase doesn't seem that unreasonable with those mods (depends how "tight" your bottom-end is). And, the VaraRam doesn't even enter the equation until your velocity reaches about 50-60 MPH, then you should see another 25+ HP on top of that!
Here are my horsepower mods:
LG SuperPro 1 7/8 Longtube Headers
SLP Blackwing Intake
MSG ignition wires
Tuned on dyno at Rocky Mountain Competetive Research in Colorado Springs, CO.
Dyno'd at 380rwhp and 375rwtrq. This is with the correction factor as we are at a 6,000 foot altitude above sea level.
