[QUOTE="Izso, post: 1064564509, member: 2429"] That's super cheap for a 421. I would doubt the quality. And I wouldn't touch the exhaust if there's nothing wrong with it since your car is stock. And your mech isn't wrong - it'll affect FC [I]if it's done incorrectly[/I]. Too large and you'll lose scavenging, lose back pressure and you'll rev more (more FC), etc. It's a fine line. If you understand what reflashing does, you'll understand it's not a good idea unless you're looking for more power. It changes the fuel maps and all that so if you're looking for FC, probably best to leave at stock map. And VDOs can't be reflashed. MMC can. Don't bother la. Erm... reset for what? Are you having issues with the car? Why do you want it to relearn the way you drive if there's nothing wrong? Besides, all the PDT1000 can do is clear error codes if you have any. Want to reset it take out the battery and leave it out overnight. Next morning hook it back up and you're done. This doesn't necessarily clears the error codes so don't expect it to work if you have a check-engine light. [B]More power = more fuel.

My Wira had plenty of oomph but at the same time if I'm careful I could get 15km/L which is normally not achievable unless you're going on the highway with a normal Wira.
