XR6 Not as fast as i thought

[tacticz]

hi guys,

just brought a AU1 XR6, and really happy with it,did the auto change thing from aufalcon.com, but what i not happy about is i had a drag with a EL/EF 4.0 and we were neck and neck i thought i might beat him by atleast a car length, is there something wrong with my car? it's done 150,000 km's i have had it 5 days and havn't done a thing to it,also what stacker unit do i need as the guy before me had it stolen?

cheers,
Dan
