i would agree simon is good he tuned my old 33 back in the day, but i know joel has a stock ecu, i also read jeff can go to any dyno so you could use morpowa dyno if you want, power figures mean actually hang on, I have bad gastro. 2 secs. ahhh thats better.. all, its the tune you should worry about.
go to ns.com n search member TSL or the speed lab topics theres a few there with dyno result pics and reviews
