Raced a supercharged e46 m3

First off, I'm not fond of racing at all, whatsoever... They were doing some pulls and pressured me to doing a couple runs with the AA supercharged e46 m3.
We did a 45 2nd gear roll and 60 3rd gear. The 3rd 60 was no good (not in favor of my car).
Needless to say, I have never really raced before, so this is new. I was surprised to to find out I kept up really well and ended up pulling him by half a car by 4th gear (VROOOOM PSSHHHHHH). And, after that I took off. Got to 150 by accident, I didn't even realize I was going that fast.

But, overall... pleased with my car Nothing to brag about, but my first race haha.

I have Stage 2 JB4, BMS DP, KW coils, running pump fuel 92 octane. He was on a built e46 m3 supercharged by AA.

7/1 Firmware Before updating firmware ensure N55 is selected under user settings to avoid JB4 defaulting to the wrong N54 tuning defaults.

1) Improved boost targeting logic. 2) Implemented a BETA autolearning map 5. Currently suitable for pump and race gas, including E85 mixes of 20% or less. For higher E85 mixes see item #4 3) Corrected bug with air intake temperature not showing in logs. 4) This firmware is the first firmware that will support the optional E85 fueling wires, which are required for those running E85 fueling mixes of greater than 20% without methanol. You may run this firmware without the wires but do not run stronger E85 mixes until the wires are installed. 5) Revised methanol map 3 for stronger low end performance and a more seamless transition from no meth flow to full meth flow. 6) If updating from some older firmwares you may need to remove keys, lock doors, and wait 5 min, for DME to reset. If logging RPM goes wacky in log, etc, post update follow this procedure.

Bentley manual confirmed that N54 internals are forged, N55 are not

And not gonna be a debbie-downer, but I'm gonna call The Stage 1 AA s/c kit for the E46 bumps power from 340 HP/270 TQ to 505 HP/365 TQ, so even with a 15% drivetrain loss that's still 430 WHP/310 WTQ. Yea, both turbo'd motors have more TQ, but unless there's meth involved I don't see this happening

Agreed.

The E46 was probably granny shifting when he should have been double clutching.
