I am in the same boat bud,
I have had my Ed30 for just over a year now, its an 08 with 33k on the clock.Whilst the remap (stage 1) power gains are extremely tempting, i have the same concerns as you..
What if the clutch cant take it? could end up costing me twice as much :(
Also what about the general drive ability of the car? does the car drive better having the remap? not in terms of raw power and torque but just normal day to day driving. At the moment there is quite a bit of turbo lag, is that reduced with the map or enhanced?
I love my car i just worried about ruining the overall driving experience.
Anybody who has made the jump have any advice?
