You get used to gauge hijacking! You will have Gauge highjacking to only come at more than 50% throttle - I think this is referred to as Stealth Mode you can switch this off (Steering control Speedo 5--Tach 6)! I have boost on fuel and Meth flow on oil - works great.
The .Hex file will take a few mins to upload, there is a counter in one of the cells showing upload progress. Once complete you are ok to start the car.
I've had some of these changes in an Alpha Map and tried map5. Immediately boosted to 17psi and felt pretty strong. Once the car is fixed of its current issues, I hope to get this all working smoothly. Smoother Transitions on map 3 sounds good, more aggressive torque combined with DTC enabled sounds dangerous in the wet!!
