I have an 03 double cab 3.4L Tacoma with the TRD supercharger, 2.2" pulley, Map 3 ECU and 7th injector. Exhaust mods are Doug Thorley headers from URD, eastern 2.5" hi flow cat, Magnaflow muffler with custom stainless steel 2.5" pipe from headers back. Also have K&N intake and filter. Truck is running 4.88 gears with 35" BFG KM2 tires. Just got the exhaust installed and the dyno run for all this is 229hp and 241 torque to the wheels...... this seems extremely low for the nearly 9 grand in mods with install, tuning, and performance built tranny. I wanted to see if everyone agrees this is a proper gain for my setup or if the tires/ gears are possibly what is killing my performance so bad? Was trying to just do all bolt on and get it to the 275-300 hp range. Done a lot of searching and haven't come across many people with my same setup to do a good power comparison.
I have a 2014 STI which is a 2.5L turbo 4 cylinder and to think stock with no mods still makes 50+/- hp more than my almost fully built SC V6 truck. At the wheels I know of course the STI is not the 305hp its rated at, but just using it as a power reference.
