Yeah, yeah, phillip, I see you say that all the time , but I think it's good to have with an S-AFC, especially if you crank the boost on race gas with extremely lean settings. Also, it costs less than $100 and is easy to install...

 

You will definitely feel a difference. The car won't run pig rich at the top end, so it will pull harder to redline. Overall, you will gain significant HP across the entire power band...enough to feel it in the butt dyno.
