I will get the topic back on track
although i always think a car like the gti should be run on v power. feels smoother to me but thats just my opinion.
2. Best Modification to the gti for me Stage 1 remap
3. Most misfires and lumpy running is caused by coil packs
4. Cambelt should be changed every 4 years or 40,000 miles (whichever is the sooner).
5. The Gti has a KO3 and the edition30 & pirelli have a KO4 turbo
6. Stage 1 remap requires no additional modifications
7. Stage 2 requires downpipe and sports cat and software
8. stage 2+ needs hpfp, intercooler, cai and software
9. HPFP is high pressure fuel pump
10. CAI is cold air induction
I think this is a great idea as time and time again these type of questions are asked. We should all add things we didnt at first know and learnt from this great site
