Hi all thought would mention this on here as you guys may have had the problem on your car at some point.

i have a 2003 focus rs which has the below items,the problem i have is when the revs are coming down when you start coasting to a junction tight bend sometimes the revs drop too low and stall, the car has been into a ford dealer workshop today who have said there is a pcm update for driveability and this maycure this. however because the car has been remaped by graham goode i thought i would see what they say before i have this pcm update carried out. i was then told by them not to get the ford dealer to carry out the update as they think the problem is down to the dump valve. So tonite i have shut off the dump valve and tested but every so often the vehicle still stalls or goes to stall if you dont rev the car. Any ideas would be appreciated. list of modifications below.

# Engine Mapped for 300 BHP with Power Adjuster
# GGR Cold Flow Air Induction System
# GGR Stainless Racing Exhaust with No Centre Box (Car sold with original CAT)
# GGR Uprated and Lowered Spring Kit
# Quaife Uprated ATB
# Bailey DV24 Piston Dump Valve
# Quick Shift Gear Lever
# Uprated Turbo

thanks
