depends on his current mods 2 date? and they r? any1 who finds a udp or pulley set (4get the alt pulley as most do, waste of ur time) a PITA should look at whether they should b doin their own car work, whether thru a lack of knowledge or a lack of automotive tools. but if placebo power in the form of more initial throttle response per gas pedal throw is what u want, go w/TB. but i'd wait on that, port ur stock TB, invest in a udp of 1 brand or another, and then take that ~150 u have left from not buyin the TB yet towards another mod.
oh i presume that u were racing each other at a track right?
