HI all,
I recently got a set of forge piston with compression ratio of 9:1. I am palnning to fix it on my gti, however I am not sure the 9:1 ratio is with or without consideration of the metal gaket?
should i buy the apexi afc and boost controller meter, or save some money and go for dastek ecu....??? pro and cons......need all help from the sifus and tok guru...
anyway my engine is gsr and moding to go around...
