hi. After a few problems with my scoob not starting it boiled down to the fuel guard on the alarm but in the process i bought a walbro fuel pump for my99 uk turbo. I thought i'd fit it anyway but now when its idleing it goes fast/slow due to the increased fuel pump rate. Will this sort its self out with a ecu reset or is it remap time? The car has no power mods just downpipe, hi-flow cat, panel filter and d/v. Any advice will be well recieved.Thanks
