my car for a while now has been slowley getting worse, performance wise...i've had to turn the boost down (1 & half turns on the rod)...i thought this was due to the cold weather...anyway last week damp got in and the car was popin' n' bangin' like a right twat....so i had a spair set of leads,and got a new dissy cap and rotor arm....all put on and drove home and thought..."the car hasn't hit over boost...umm"....so i wound it up half a turn....still good...lets try a full turn now.....FOOKIN' HELL...MAGIC...the cars back to how it was in November when it was mapped....simple servicing and checking of "cheap" parts....just thought i'd share this with u all, cos how many times is it the simple things, that can cause such grief...cheers Pete....
