have lower pulley and new file whats the hp gain with a upper pulley??? thanks in advance

 

I have a V6. Have not dynod but just installed the upper pulley and stg3 file last week and the car is noticably faster. I was not expecting to feel a real seat of the pants difference but wow. It used to be a little flat at the top of the rpm range but now pulls hard all the way to redline. Really woke it up. Not sure if that helps you given it looks like you have an R but I was thrilled with the results on my 6.

 

About 25hp but will need a new tune which if you've had the last tune from vap they'll do a new one for free.

 

It would be interesting for me how many tenths of a second Stage 2 brings to Stage 3 with the R AWD V8. Has anyone had any experience with VA on this?
