Basically my car has a ko4 turbo, forge fmic, s3 injectors, air filter down in the bumper not sure of make, forge DV and a Sachs clutch . Apparently it was running 340 bhp but It developed a misfire so I took it to jabbasport and they told me a remap would sort it but it hasn't and they told me it came out at 310bhp, told me they will send the dyno printout in the post as they was out of ink but I still haven't received it after 4-5 weeks and a phone call.
(Missed out full milltek and hpfp)
Should I be at more power than that and where do I stand with getting some money back as they said I need a remap but it hasn't fixed it ? Any opinions/thoughts would be great :)
