Finished the 2nd mild upgrade on a recent short block V6 purchase. 18K on the new block, put xpipe duals 2 1/2" pipes and CAI. Not looking to burn tires off the car, wanted to attempt increasing throttle response. Would a slightly larger throttle body be worth it? Still using the original, untouched. This is not to be a race car, just a fun cruiser. Open for suggestions, short of, "sell the car, buy a V8". Been there, heard that.
