Spartan tuned 6.7 first impressions!!!!!

Got to spend some time with Matt at Spartan tuning my 6.7 and here's my findings and impressions so far. To start this truck is a CC/SB with 8" of lift and American Force Supersingles with adaptors and 37" Dunlop Maxx traction tires. The truck went down from CT to Matt's in NC a few days prior to the shootout at Rudy's Diesel/ Aaron's running on a H+S mini max. On the way down the truck averaged 15.1 MPG hand calc using a Garman nav for miles travelled(speedo was still slightly off due to me playing with tire size on the H+S and gear ratio with my IDS software). After spending the day with Matt and trying a ton of different programs I left to cross NC to Rudy's Thursday night. First impressions were that the throttle was much more responsive and the turbo would spool up faster from a flat foot/dead start. Based on the smoke from the tailpipe the fueling is much more aggressive, and spool up is reduced greatly from the H+S. Next was the trip across to Rudy's, which truck ran great and seemed to "learn" and become faster and faster as I went. The transmission still seemed to love the power as it did with the H+S, and it just never missed a beat. Roll on acceleration at highway speed is nite and day different between the two programmers, at 1600 rpm it just comes on. After helping Aaron get things ready at the shop Friday, we strapped his truck to his dyno and made some pulls and got a peak HP of 468hp(no torque numbers, dyno just got installed and we were in a rush). After picking up Mike from Diesel Power, Chad from Flynn's Shop and my son at the airport we strapped my truck down and made some pulls also ending up with 464hp. I wish we took the time to get tq numbers as I believe based on driving both tuners the Spartan tune would have had high tq numbers. The tire and wheel package on Aaron's truck was a much lighter 35" ish tire on a BMF wheel, so I know my heavier rolling stock cost some hp. As another side note, my truck was only making 20ish psi boost on the Spartan tune were as it made 28-29 on the H+S. After talking to Matt Sunday, he has revised the tunes somemore and is now making 28-30 psi boost. Power is up a great deal more, can't wait to try that revised tune. The trip home was made running the Spartan tune, and Mileage was up almost 1.8 MPG, but I only checked til we got nearer to home because Sunday night traffic was stop and go. I think this is great news for 6.7 owners as competition like this creates better products for the end user! Can't wait to see what Eric and Innovative have, as I know he's close to finished also.

It has obviously been a long time since this topic saw any activity. We just wanted to let everyone know that we are still here, and strong. We also recently released a tuning update for our existing 6.7 customers.
