I have the n75J in my car... I have not gone into limp mode and I have had it for months with the APR stage 1 93 octane chip. I am upgrading to the stage 1+.. I am not sure how the n75j will like that but its worth a try. The guy from APR told me to get the J and that the H is a little more aggressive and will lead to more problems on the b6. I dont know how valid that statement is but their advice is usually pretty good.The H seems to work for a lot of people though.. including onepoint8tee. If you have b5 go H ... if you have a b6 go j maybe?

 

alright its settled then, im buying a N75H

if anybody wants to know my results, go ahead am pm and ill tell you how it is in about a week

 

I'd get a second opinion. My car has been to Audi several times supposedly replacing all bad vac lines. not until this last trip were all my vac leaks corrected even though ever time Audi said "all fixed empty your wallet in the bin next to the door on your way out"

 

i think ill do that.

personally, the stealership is the last resort when it comes to help.

not too many places around here that specializes in audis, but ill look around and get another opinion.

good idea, thanks
