    Mods in signature MINUS the Downpipes....not installed yet. These were done on the same day in a temperature controlled room.

    I like the gearhead tune. What's up with the a/f ratio on the livernois? I like the steady a/f of the gearhead. Not that I know anything.

    LMS doesn't lock the gears in sport mode.. so we couldn't go WOT until close to 4K rpms or it will start to downshift to second gear.. thus why the enrichment looks funky.. Unfortunately I called LMS several times and a day or so before the dyno was scheduled to inquire about their recommended way to run their tune on a dyno. I was aware of this issue before hand so was hoping to mitigate it before. You can see the blue line has an artificial spike at around 3500rpms because it started to down shift but he was able to ease off the throttle intime..

    They have to have a preferred method or they send a tune that can lock the gears in place with the paddle shifter.. looking at their dynos, it appears they don't have this issue. It makes comparing the torque under 4000rpms impossible as its not WOT from that point backwards.

    Wow, that's fantastic. I don't have or don't know of a 4 wheel dyno in all of Arkansas but I'm looking at one of those apps that uses GPS to measure my 1/4 times to figure my hp/tq.

    SBS's SHO is almost a full bolt on car. So his power level is well above just a tuned car.

    Turbos and Downpipes are purchased... shop is looking at a mid April install time frame with a bit of dyno time to dial it in.

    Looking to get it dialed at 475/500 at the wheels.

    Very nice! Kind of the same theme here when I compared my LMS 93 to the new GH Auto Octane tune!

    Just like my comparison on my thread. Is yours a true apples-to-apples comparison? LMS was same exact mods, e30, etc?

    You can’t get a better comparison. Literally drove the car 1.5 hrs to the shop with the GH tune loaded. They put it right in the rollers, turned the massive fan system on, did two pulls. They left the fans running while I reflashed the LMS tune while still on the rollers. Verified that learned octane and fuel trims were still set correctly. Then did two more pulls. There was about a 1/2 hour cool down before the LMS tune was run with the fans blowing sub freezing temps on the car.
