I ran across the STS site and it looks interesting and I'm interested in a system as well. However, I thought I'd turn to the Club members for more input. And yes, I exercised due diligence and searched the subject. While I found some interesting information I did not find exactly what I need to know. For reference my truck is an 07 Classic (38,000 miles) with the 4.3L engine, 5 speed manual, and bolt on mods (underdrive pulleys, shorty headers, Gibson 3" exhaust, K & N CAI). My driving is about 90-95% rural county roads at about 1200-1500 rpm's. And the rest is highway miles. What I would like to know is folks experience with the turbo. Specifically, and this is very important, is anyone running STS set up with a manual transmission? If so, how does it perform? Was it easy to install or would you recommend having it installed. Does it perform as advertised. Would recommend the product.
