Im running 190's with a 03 turbo and with Chris B's tuning it runs SUPER HARD and burns as clean as it did before the 190's. Im going to go with this setup for a while, I honestly couldn't justify the Powermax price if you're not looking for ground breaking power, the 03 turbo will still put down just south of 500 with proper tuning and capable injectors.
I'd rather have a fuel system and ficm flash, or a gogo stage 1 intake over the powermax.
I've been contemplating the idea of going two different directions. And right now there are setups that can make proven power, but I want to try and make 520 to the wheels with a 03 turbo and no nitrous. I think Its more than possible with a drop in Batmowheel, ficm tuning, and doug's stage 1 intake on top of my setup currently i think Ill be there with live tuning. I sure dont expect to be the fastest truck, I want it to be quick, and fun to drive, with being reliable and driveable. Right now My truck drives like stock and it makes awesome power and I kind of want to keep it this way but a little bit more.
