Hey guys,

I just recently bought a 2001.5 s4 that has bi-pipes, diverter valves, downpipes, intake and full exhaust on it. It came with a stage 2 J-Fonz tune which as i found out was pretty bad for my car. It was very fast but the combustion temps were through the roof. So i had it tuned back to stock mainly so I could pass emissions. Now that im through that I want to get it back to where it was on a little bit safer level. I've been thinking about GIAC or REVO but am really considering anything at this point beside's J-Fonz that is. Does anyone have any software that they particularly like/would recommend for a Stage 2 tune?
