I was at the June 28/29 RMW tune at the Speedfactory in Seattle. I have a 15% Alta pulley, Dinan CAI, Brisk plugs, and a 539 belt. Unfortunately the belt slipped in the upper range but overall I think it was a decent result considering the mods. Please post yours if you were there.

 

Wow! Great results! I'm having RMW tune my car in Eugene on the 10th. After seeing your results, I'm really looking forward to it. I have pretty much the same mods as you, but with a catback added, and the 537 belt. That belt is a pain to put on if you don't have the tensioner tool. Anyway - can I assume the dips in the torque and horespower curves are a result of the slipping belt?

 

After the dyno and talking to some other members, I'd recommend you go with the 535 belt rather than 537. Have fun and bring a video camera and earplugs.

 

DOH! Yeah, sorry - I did go with the 535. I was going to go with the 537, but after doing some searches here on NAM, I decided to go with the 535. Definitely the right thing to do.

 

Still very good delta's
