2012 vw tdi
Hello everyone, I'm new to the tdi car seen and I'm trying to figure out the best way to prep my car for more power. I have a 2012 tdi golf. I understand most people swap the cjaa but I would rather do anything to get this engine running at the most 250hp/300 to 400 foot lbs. I would really appreciate any tips and tricks. Thank you.

My 2010 has the CJAA eng. your 2012 has a slightly different eng code. not sure but maybe CKRA? To up power, most don't do eng swaps but ECU reprogramming, with swapping out injectors, turbos, exhaust, and clutches. A little searching on this site will find a lot of info on it. Malone and ECS Tuning are 2 places mentioned a lot on this site that might have info on this. Remember, changing or deleting the emissions system on a car that is driven on the road is illegal. So be aware talking about it.

oops my bad. I guess the 2012 does still use eng code CJAA. I should have learned by now not to talk before thinking.
