TRD Supercharged Toyota Tacoma - Engine Tuning - Split Second
A TKO For Weak Performance
About a year ago, we did an installation article on a TRD supercharger for the V-6 Tacoma. Since TRD offers this upgrade as an addition for all V-6 trucks, we figured that installing the supercharger would be a simple bolt-on deal, with no negative after effects. As it turns out, we were wrong. The truck simply wouldn't put out the kind of power we'd seen in S-Runners and other TRD-built performance trucks, and we wanted to know why. Having never really received any straight answers and running a "pinger" pulley on the supercharger to keep it from detonating, we contacted the Split Second crew to install one of its Fuel/Timing Calibrator engine management boxes.We then dyno-tested the truck to create a map for it, which would allow it to boost and actually create usable horsepower. Before tuning, the truck made 140 hp and 202 lb-ft of torque. What we ended up with were answers to some long-standing nagging questions about the supercharger and a boatload of horsepower than we hadn't previously seen. We still have some tuning to do, and there's still some untapped horsepower that we feel we can get from the truck, but the amount we picked up just by adding the box and tuning the fuel map was amazing. Follow along and contact Split Second using the information in the source section to find out how the crew can make your truck perform like you never thought possible.
