Chip Tuning for Cooper S Turbo

My R56 MCS made 170 whp and 202wlb-ft at the wheels, stock. I have the MAF, MAP, IAT, and timing datalogging and BSFC and VE calculations to corroborate the dyno measurements, so it checks out, none of this "not properly configured" crap. For reference, my stock R53 MCS made 157 whp and 142 wlb-ft on the same chassis dyno using the same operator, also using 4th gear, using the same SAE atmospheric correction factor.

When an ECU product does come out, the gains will be by smoothing out the boost curve, and bumping up the boost a bit to perhaps 16psig. I have a feeling most tuners will be afraid to push the GDI-T setup too hard with that 10.5:1 static CR looming, as well as the new kind of ignition and AFR targets that are very different than with port injection engines.

Cheers,
Ryan
