Theres got to be more to the mpg loss than the tb spacer.

I'm about to install a meth system here shortly so I went with the boomba spacer vice the Steeda one because of that (should have gotten the one from Full Race)...anyway the 2 weeks or so I have had it on I've noticed a decrease in mpg as well. I know the gas here is shittier now and I have been changing tunes so It's tough to pin it directly on the TSB but I'd say it's a part of it.

1000 mile update

1000 miles later, down 1.4 mpg. Butt dyno inconclusive. Not a total loss, I have someplace to inject meth now. I may take spacer out and see if mpg recovers.

Removed Spacer

Removed offending throttle body spacer. I know it's just 22.4 miles (my one way commute to work) but 28 mpg! I've never seen 28 mpg before!! I'll check mpg after a few hundred miles, but can a 3/4" spacer have that much effect on mpg?
