APR or GIAC or ...

I have a Audi TT Quattro 225ps and am looking for more power/torque.

I also do not want to solder a chip in my car.

Who do you think offers the best product?

Abt. Do a search for John s' posts on the TT forum. He's posted lots of nice comparison plots in the

past.

GIAC X chip or std APR you'll have to solder, same with ABT...

GIAC X chip is the most powerful apparently right now. You can get it with an IBE chipswitch to change programs like APR's EMCS. REVO has the non-solder solution with their upgrades, which are very nice IMO. APR has been having trouble with theirs apparently from some reports from waterfest having the cars kept overnight to fix them.

THe x-chip logs that I gave to JohnS

aren't reliable.. During the time at which I took that data my car wasn't running 100%.. I was having problems with my N75 valve..

I wonder how the O.CT chip is compared to the Abt and others...

I thought that the GIAC ran at like 1.2 or 1.3 BAR and that's why it had more power and torque. Is that correct?

I don't think that they're supposed to really run any more boost...

Though it seems like some people have that. I am sure that the OCT is good, but I don't have any basis for comparison. Just by GIAC's work on the 959 Porsches, and their long history with Audi and VW, I give them the nod personally. That and their Silverbullet S4 too.
