Sorry, maybe I was a little unclear... I was considering going for either the GTEC1 and PRV (and boost guage) to give +30BHP or to opt for the rolling road (power engineering) and engine tune which they claim will give +40BHP for £470...
Any advice would be great fully received. Thanks.
yes, go somewhere else. The Gtec+PRV+boost gauge is fine for a little more power, then a rolling road to check the fuelling, there is a rolling road session going on in surry for £40 in november.
I would be interested to know exactly what you are getting for £470 when
