So basically i did a lot of reasearch into the APR ECU Upgrade for my Audi A4 2007 2.0 just to have the shop that i was going to tell me that all they do is REVO upgrades. They tell me that it will give me more hp than APR and that it is better. Are they correct or do they just want to sell me their product instead, what are the differences and are there any known problems down the road with either of these.

Thanks

 

Revo is better IMHO. Revo offers a 5 hour free trial so why not try that and see how you like it.

 

Try it! I have a B7 too tell me how you like it and tell me what the dealer says when you go into service it!

 

will do, they tell me that the warranty is unaffected by the REVO though. I read something about it being undetectable and such.

 

Oh no its detectable, if i couldn't find it with the scan tool all i would have to do is a boost pressure test, if its higher than spec and the wastegate is functioning fine i got you.
But i wouldn't worry about it, the dealers don't really check for it, un-less something crazy happens like you blow the motor then they might look into it.

 

APR and Revo are both as good for B7. It really comes down to which dealer is closer to you.

 

So Auditech79. Your saying that if i Chip my B7 i shouldnt worry about my warranty being voided??

 

Nah, most mechanics want to get paid, they could give a flying f*** whether its chipped or not. I deliberately fixed cars that i know were chipped, audi expects us to report if the car is chipped or not, but on my crappy *** pay..........they can blow it out their *** as for as im concerned.
There are a couple hard core techs you might have to watch out for, but 90% of the time its no big deal. Audi actually released a private TSB for identifing chipped software a few months back, most of us threw it in the trash.

 

What happens if you get caught with a CHIP?

 

Its up to the technician, if he reports it to audi the powertrain warranty is completely voided.
This has only happened once at my dealer though after a guy with a 4.2L S4 blew the motor at 14k on the odometer. That kinda crap throws up a red flag, it turns out he over reved the motor and smacked the valves into the pistons. $28,000 repair bill not covered.
