Hi all! have had my bug eye in the garage 4 missing problems and they said they couldn't bring up any faults.. The missing doesn't seem to be so evident now but the car is not the same car as when i bought it I even have a job keeping up with my dads audi s2 avant which is running at 230bhp? The car sounds rough and is very hesistant when I floor it, it sometimes stutters then goes but the power it used to have just ain't there? and other times if I get in the car to start it, it wont start first time? Any ideas?? Have recentley fitted a bailey dump valve can this cause problems?

Thanks in advance!

 

Stick the OEM Dump Valve back on and find out.

If you search on this site you will find a few posts that have suggested that an aftermarket dumpvalve has caused similar problems.
