I have a 2000 GT 5 speed that I am currently gathering all the gear needed for a Rear Mount turbo set up. I have a predator tuner on the way, and will installing a wideband o2 sensor. I am currently stationed in Yokosuka, Japan, so a dyno tune is out of the question. I have two questions, first, will a predator MAF extender allow me to use my stock MAF, or do I need to go with a Lightning 90mm for 42# injectors, and second, how do I get a custom tune sent to me via email for the predator? I plan to boost 6.5 psi, and stay between 11.5 to 12.5 A/R, I believe this will put me in the 400-450 rwhp range. I know it seems difficult, but I gotta rip my buddies Skyline GT.
