Got my E89 20i remapped by Will @ Performance Torque last week. Absolutely lovely bloke, and he's been more than happy to help me with some questions I had after the remap as well. He managed to fit me in really quickly due to a last minute cancellation, otherwise it would have been at least a 2 week wait. The customer area is lovely and private, with a TV and Xbox which you can use. Although, to be fair, you can't really hear anything once the dyno pulls start happening!
Firstly... Holy moly!
It pulls like a train now. Biggest improvement for me is the low-end oomph once you're in boost. Makes it so much better as a daily driver.
I live in the middle of nowhere, and the 'main' road is a 50, with not much visibility either way, so you really have to commit when pulling out (no double entendre intended
). Previously I really had to be careful with the auto 'box so that the revs didn't go too high on a cold engine (sometimes I'd need to use the paddles etc. to get it to shift earlier). Now, with the remap, I don't really need to worry about that at all, as it's got enough power low down that it can afford to change gear far earlier.For anyone who hasn't experienced it, to me it's effectively like the car is in sport mode permanently (minus the different shift points). You've got the sharper and more aggressive throttle response all the time. Now, the actual "Sport" mode is just awesome.
Pre-remap, at motorway speeds with the roof down, it'd need a fair bit of throttle just to keep a stable speed because of the massive amount of drag generated. Post-remap, that's far less of an issue.
Got it done on one of the muggiest, most humid days of the year, so cooling/intake temps were a bit of an issue after a slew of dyno pulls, so it was making 245hp as a worst-case scenario. It's running the same boost level as the other 20i's he's done, which he's said generally make about 260hp, so realistically, it'll be making about that in day to day driving, and will only dip down to the 245hp mark if it gets super duper toasty, or if it gets absolutely ragged.
Haven't got the dyno graphs yet so not sure about the torque, but will upload them once I do.
Happy to answer any questions anyone has!
