After installing the CXRacing Intercooler and setting up my car as a draw-thru system, I brought the car into Wicked Motorsports to have Kevin Hand take a look at it. We determined that the car was tailing lean and found that the CXRacing Intercooler was loosing 4 - 6 PSI after logging it pre and after. As I said, the car was set up as a draw-thru system which means the location of the MAF (Mass Airflow Meter) was just after the K&N Filter . That means the air was being measured right after the filter rather than right before the throttle body. I didn't like the fact that the air traveled through the piping, in the intercooler, through more piping, then into the engine. The readings cannot be 100% accurate that way, so I decided to change it. We relocated the MAF to right before the throttle body which means we converted the from a Bypass Valve (which recirculates the air) to a Blow Off Valve (which blows the excess air into the atmosphere). My fuel pump was also struggling a bit up top so I picked up a .

*UPDATE* Here we are 5 years later and the car is still running great! A year or so after this post my MAC long tube headers bit the dust, so I picked up some American Racing Long Tube HeadersAmerican Racing Headers and Offroad X-Pipe and gained even more HP. The final #'s are below.

Dyno Sheet Before American Racing Long Tube HeadersAmerican Racing Headers & Offroad X-Pipe

#'s before headers / x-pipe - 444 RWHP / 413 RWTQ. First run on the dyno was 408 RWHP, this was with the Treadstone intercooler. The next run, after the new intercooler and customizations (but before Headers), the #'s were 444 rwhp. So I picked up 36 RWHP when ditching the CX-Racing Intercooler.
