I'm sure all of you TBI guys are familiar with TBI chips.com. This dude seems to have the TBI mods down to a science. Anyway, I just got the upgraded fuel pump he reccomends, also have the Flowmaster Y-pipe & heated O2 sensor sitting here ready to go. I've been waiting to year apart my exaust because I'm torn on wether or not to install the headers I have. I hate leaky headers! I think I'll go ahaid & put the headers on & the dual 2.5" into 3" y pipe. I'm also torn as to how much money to put into the TBI. I know eventually it will end up with an LS swap. But $100 at a time is way easier to swallow than $2500.
