L31 TPI TUNE?
Hey guys,just installed an l31 crate motor in my formally lb9 iroc. motor is stock minus headers and injectors. im still running tpi intake and factory ecm. im located in alabama and im looking for someone that can tune my car for me. i dont mind driving to surrounding states if needed. the car actually runs pretty good with 305 tune but i dont know if its running lean or not so i dont want to burn it up. yes im willing to pay..please let me know or pm me..thanks

AEM makes a nice wideban gauge with the controller built into the gauge. About $160 on Amazon. Get the bung welded into the exhaust, install the sensor and wiring and take the guess work out of it. Car definately needs 350 injectors, knock sensor, knock module iff applicable and some computer tuning to get the most out of the Vortec heads.
