Hey whats going on guys, I recently got my B7 and it is completely stock. I got the 08 A4 quattro. I come from the Honda world, I used to have a 08 Honda Civic Si, which comes with the 2.0 high compression (11.1) high rev engine. And it used to be turbo with a gt35 garrett turbo at 12.5 psi which made me 424whp at a dynojet.

I sold the Si and got the audi, love it, the way it looks, commodity, ride quality, everything overall its a way better ride. As performance I know from the B7:

-10.5 compression
-2.0 liters in-line 4 front engine with 82.5 mm bore, 92.8 mm stroke
-Double overhead cam, variable valve timing/camshaft and four valves per cylinder
-Makes 200hp and 207tq (love the tq part, the si only had 137tq)

My question is, any personal opinion on the APR chip stage 1? Im looking to get on my automatic transmission, but since it is the quattro, with the AWD and paddle shift where i can make and hold my own shifts, any good or bad experience or recommendation?
Also any actual dyno graphs for the gains? I have seen the advertised gains on their website, just like to know what you guys experienced. thanks!

 

I have APR on my CVT, and I'm very happy with it. It holds about 20 psi up to 3.5k RPM, and then starts to taper off.

 

apr is a good stuff

 

Oh ok cool. What psi is the stock turbo running at? Sorry for my ignorance, what's cvt? The tranny?

 

CVT = continuously variable transmission. stock the psi is about 10-11.

 

what chip does not cause the check engine light from turning on?

 

why would it throw a cel? i thought that the flashing takes care of that? at least the apr?

 

i heard APR doesn't cause it but REVO or GIAC does.

 

Flashing with any chip should not cause a CEL. Removing your catalytic converter will throw a CEL, which most of the chip makers have a flash to override.

 

I have a REVO and went through Stage 1 and Stage 2 without any check engine lights. If you have a downpipe and don't have a spacer on the rear 02 sensor then that will throw a CEL. But if you have a downpipe and exhaust then you dont need the rear 02 spacer. If you have a spacer on with both (downpipe and exhaust) then the CEL will pop on. That has been my experience.
