Hi Kim, I have that exact set up on my car, and the "butt dyno" tells me that the engine is more responsive and pulls harder in the top end. I send my Steve Wong chip back for a (reflash) upgrade, when it gets back, I will get Zensport to do a back to back dyno test between stock vs. SW chip, will post the results.
