I lied. The swap actually managed to shave my 0-60 off 1.6 seconds... Now it's only 11.8 :-(... Aw well. I leaned it out some by raising the idle through the screw and leaning the idle screws so now it runs better but still seems a tad slow.
How are you checking your 0-60 MPH times?
I use a Belltronics FX2 meter, seems pretty accurate.
