fd help
Hi there
I just got my fd put on the dyno to get a new boost controller put in, had the plugs changed etc. running an extended port 2mm seals big turbo etc. after 6500 rpm the car was miss firing tuner wasnt sure why and we didnt want to push it any further. got 220@wkws at 6k around 17 pounds. whilst thats fine, why is the car miss firing, would it be the coils and leads?
on another note the compression is 70! which seems super low. the car doesnt run badly though sometimes when its cold it needs a little gas to get starting but then idles fine? is it expected that an ported engine with 2mm seals opposed to 3 would run lower compression?
any help would be fantastic.
cheers
