I ran my truck on a G-Tech yesterday to measure the horsepower & it said max of 135rwhp. That seems like a lot of drivetrain loss to me. My motor is a '93 vin-W CPI with a few mods; headers, full 2 1/2" exhaust, 3" custom intake w/ 9" K&N cone filter, 180 t-stat, b&m shiftplus, corvette servo, & bumped timing. It has 3.08 gears, peg leg traction, & weighs in around 3800#. The truck has been taken real good care of maintenance wise, but it does have 200,000 miles on it. Maybe its time for a trans rebuild. Does this figure seem right to everyone else?
