Here are my dyno sheets from my E-Force install with a custom tune. Stock 07 A6 with E-Force, AR 1 7/8" headers with Hi-Flow cats and NPP exhaust. My torque number is higher than my HP number, something I haven't see before.
I'll bet that thing is fun to drive!
I've got some work to do - smaller pullet and a BAP!
The change from the 3.875" to 3.5" pulley isn't a big gain. You get about 1.5psi and 45 flywheel horsepower.
That's true I suppose but won't my 52 lb. injectors restrict going to even a smaller pulley. Also, I don't think the current canned tune would be sufficient for a pulley smaller than 3.5".
I think it will cost me about $325 for a pulley, harness and BAP. Pretty good HP bang for the buck though.

All true....you are looking at about 35rwhp on a 475rwhp-ish car. It won't be a huge kick in the pants difference.
