I had linear throttle on my MK5 in 2008, I asked REVO to do it and they did. How linear is was I don't know, but I know it worked and it was exactly how I expected it to be.
It's thread is the OP asking for a 'you v REVO' comparison, so any comments you make about sales tactics, quoting bluff figures, blah blah blah can only be assumed to be your opinion of REVO? Sorry, that's how it reads to me. I'd say the same if it was APR or anyone else...
