Hello, i was checking out rpmoutlet.com and they seem to have a pretty good site....i saw this package on there... http://www.rpmoutlet.com/newv61552ins.htm ...i was wondering if it was worth it ...it comes with a MAC cold air kit, a BBK 70mm throttle body, and motor/vator t-body spacer.....the price is $460 and it says you get gains of 28.2 rwhp....im not sure what the throttle body and spacer does but is this a good price for this kit and is it worth it? or is the site embelishing on the gains? thanks a lot for the input!
