Sounds to me like he should just leave everything off and not bother putting it back together. lol

 

yea, if it gives him that much power, why put it back.... maybe gas mileage, or him not wanting to stomp on in as much.... but non the less... he wants to go to a dyno ( down the road) and get it tested, with and without the spacer and see if there is a differance..

what do you guys think he will get?

 

nuttin' unless he tests without first then with it on. It's very common that a second dyno run is stronger than the first.

When the manufacturer says you'll see NO gains on the dyno, trust me, you'll see NO gains on a dyno. It's his $, let him waste it...
