Hello there. I just acquired a 1993 k2500 with a 5.7 tbi. The intake manifold was busted so I have pulled the engine apart and going to a full rebuild along with a few performance upgrades. I am not sure if I will even need a chip for the upgrades, that's why I am asking for your honest help. Its a standard bore and stroke. I am installing vortec heads with maybe a gasket match port and polish along with maybe a 3 or 5 angle valve job. Also I will be installing a new distributor with a hotter coil. And a carb intake with a tbi adapter. Of course the tbi mods will be done to the throttle body. And also looking to install a melling mtc-1 camshaft. Later on down the road I'm going to install long tube headers, flowmastef y pipe and high flow cats. Maybe in the future as well have a functional ram air hood and roller rockers installed too. My question is, will I need a chip or a tuned ecu? If so which chip will I need? Thanks again for your help it is much appreciated.
