New Dinan Stage 2 Ecu Mod.
Dinan came out with the mod end of last week and I put it on this Monday. Dinan skipped the State 1 since they said BMW had already provided that with the car stock. I had the Dinan Stage 2 on my 2008 335I and loved it. The new ECU mod for the 1M has the same performance specs 380 hp and 415 torque. I just left Willow Springs Race Way after doing 5 thirty minute sessions. I was on the track two months earlier and I can tell you the difference since doing the Stage 2 is amazing. There is no maximum seconds of over boost, it comes on earlier and last to the top of the rev curve. A very light increase in pressure on the pedal when in a high speed curve still provides more power and acceleration on a smooth exit like in turn 2 and 8. The warranty match also seals the deal for me.
