Re: L31 TPI TUNE?

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.
