Hi Jason,
Nice to see a fellow Teamwave runner in the UK...
I found running the FRD lower, my turbo did not kick in early enough and was peaking on a sweeper (out track is square, so the straight always has a nearly flat out 90 right in it!!)
I tried the gearing of 7.2 so it would kick in earlier due to the speedo settings being activated (so to speak) but the RPM.
That being said I am still lacking some puntch to a well sorted Tekin driver... so maybe more fettling is needed heheheh
if you ever have any questions or help, just ask away
ooo forgot to ask... do you run a motor fan?
