Hi all,
I had v3 of APR and have now been using v5 for the last month
or so. I am not sure what these
CEL problems are you guys are talking about. I don't have any
errors that I know about - but I dont
have a vag

The differences between 3 and 5 seem very slight. At first I
didnt notice anything... but it seemed like
it MIGHT be slightly less powerful. It is definitely more
smooth. Less peaky. But after some time I
decided that it actually does feel more powerful (5 is better
than 3) but because it delivers that more
power smoothly its almost less noticeable. I also had a new
TBB installed at the same time, so
maybe my new Kevlar TBB is also causing some of my better
performance.

I made a call to APR to ask what they changed, and was
it 'more' HP than before.

They told me they didnt have final dyno numbers, and once
they did - those charts would be
updated on their site. But they are now stating about 325hp
with the 93 octane program.

Adam
