NEW!!!

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

1/4 mile shift optimisation

I finally got a chance to race the GTS on the new tune, with some drag radials. Pretty good success, with a 10.4 @ 138mph with a 1.60 60 foot. I did get a 1.59 60 foot in another pass, but didn't manage to get the same MPH.

So, I've attached a log of the first 2 runs of the day, hoping you can have a general look for anything that can be improved and also check the shift points? The first run of the day was my best one, which is the first one in the log. I think the 3 to 4 and 4 to 5 shifts are a bit soft, a bit slow and a bit early? They felt that way on the track compared to the 1-2 and 2-3 shifts. And possibly the 1 to 2 shift is hitting the limiter?

I've also attached the latest tune the car was running for these runs
