Hello,

I recently bought a '88 IROC Z28 TBI 305 5 spd 3:08 vert that runs fine, but seems to be as quick as an old VW Rabbit diesel. In the past I have swapped a 400 sbc w/vortec heads & a mild hyd rllr cam in my '79 Corvette. Those 3rd gen Z's were quite the poseurs.

Read & somewhat familiarized myself with TBI tuning on your "competitors" site, Thirdgen.org. EBL, data logging, laptop connectivity, mail order chip tunes, & the like look to be quite intimidating compared to slapping on a carb, a plain HEI, & a Mallory 4309 pressure regulator.

In my case, the learning curve would be just about vertical starting out. Just found this site, & boy is it thorough!
