Skyline motor Datsun truck

One of the most interesting things I’ve worked on to date. Straight out of Japan RB25 nissan skyline motor in a Datsun pickup truck controlled by an AEM EMS computer. He had taken the truck to another tuner to have it calibrated and the fueling was so far off the truck wouldn’t even make a full pass down the track. 3 pulls on the following dyno graph show the story. Green was before I tuned it, blue is low boost, red is max boost.

This truck was completely stock when it came in making 322hp/325tq. After tuning it made peak power of 334hp/344tq.

MORE IMPORTANTLY look at power under the cover at 4K RPM it picked up 50RWHP/RWTQ!!
