Don't forget to add a Bully dog tuner and stack it with superchip as well so you get the extra gains with all that new found air coming in

Thanks everyone. I finally fired it up and let it idle. What a difference! Idles WAY higher. Should hopefully raise my shift point by the same amount

that's where I got messed up. I didn't think you could use a left handed crescent wrench to tighten bolts. Only loosen them right? Are you sure it's on all the way?

No, it's exponential. 5^5^5.

Took it for a quick drive today... Insane! Could barely hold it back with the brakes! Didn't even get a chance to hit the throttle it just wanted to go. I can only imagine when I actually open it up. According to math it should rev to 9000+ at WOT!

Good point, not using a washer or an improperly calibrated washer could result in possible blinker fluid boiling, which may allow spark past the spark plugs. Always use the best washers available.

You absolutely can use a left handed crescent wrench, it just has to be metric.

I assume your running a thinner gasket in between that spacer to raise compression ratio

I would say one of the biggest things is to make sure that the spacer is placed BETWEEN the tb and intake
