Interesting , he has a diagram for aiflow meter to MAF sensor , I wonder if there are any other mods and how he is doing the tuning on this.

Was hoping to see something finished and making silly power, a bit disappointing to see it back in with standard head and inlet.

will be much better with the TBs on, but has got to be crying out for a proper big snorty airbox and alpha n or standalone management to run maf-less.

I think he used a piggy back system to eradicate the AFM

Below that diagram, he mentions the use of a Dastek unichip.

I always thought that you couldn't spin the engine above 7.2k-7.3k due to harmonic damper? is there really much point in changing to solid lifter from the M3 without sorting to this problem first?
