Just had a talk with Hans at ESS. We agreed that I'm going to try get through the periodically check. If they question the power gain from the SC unit, we'll re-program the ECU, show them a dyno showing a max of 277BHP, and the re-program the ECU back again after the check.
Thanks so far Hans :-)
Check will be on Oct. 2. - I'll post the result here.
