Finally got it installed - the shop couldn't get the brake booster / master cylinder on, so that is still something to do. Initial response: brakes feels much softer than stock, the mechanics were so worried they re-bleed twice and wasnt comfortable with me driving away. I find it drivable, but wasn't very confident with ebrake.
Got it coded today and to be honest, couldn't feel a big difference with before i code. So until I get the master cylinder changed, won't be able to tell much.
