I specified 25% reduction anticipating a pulley upgrade that hasn't come yet and now I'm running rich. I would specify a 20% reduction with the LE pulley when getting your ECU tuned. You should see a 20 rwhp difference with both.
I think the ASP pulley is in the 170's but I'm not for certain. The LE pulley is 185mm, and the pulley I'm custom making at a machine shop is 192mm.
20 WHP!!!??? With the Pulley setup and ECU tune??? That makes no sense. If that is true then it's TOTALLY NOT WORTH THE EXPENSE! How much does the Renntech kit add?
Is there a website for the ASP pulley? I found their website, but searched it high and low and could not find anything for an SRT-6, a C32 or an SLK32... Am I missing something ???
