Hey guys, new user here running a 2001GTI-6
Had that awful day of days with a recently acquired car when you take it to the rolling road ang get nothing like standard power from the run.
Car is very tidy, doesnt burn oil, was getting decent CO which suggests mixture was fine and was running 99 octane which might be a little high for a standard ECU?
Also runs a powerflow backbox which i will probably replace as it achieves little.
Result was 136 est flywheel bhp, about 30 down on standard on a well serviced car done 90,000 miles. Which suggests domething is clearly amiss.
OK, i am not daft and would expect an older car to lose a little power over time, but 30hp us a fair bit.
Any suggestions or experiences from you guys?
My next course is a diagnostic to see if ECU throws any faults at me, perhaps a compression check and maybe an injector clean. Other than that I am not sure.
