I'm trying to figure out what is causing the lack of performance in my gti6, had it for a year it's got 97,000 miles on the clock.
I'm suspecting the fuel pressure is low i've ordered a pressure gauge tester and a fuel filter and i'm gona test it on wednesday hopefully, i will re-post the results.
I can't think what else affects performance: air filter is clean, spark plugs renewed last year, as well as oil changed, practically new (standard) exhaust.
