I haven't tried putting it in CL in months so couldn't tell you. I'll try that tomorrow. I calibrated the WB to free air a couple weeks ago and it is grounded to the same wire comming in from the block to the pcm. the funny thing is this only happens on the hwy. It runs pretty good any other time. just running around town its fine, good throttle response, takeoff power, dosent struggle to get up to speed. I know its about arodynamic as an umbella at those speeds and trying to turn 75lb a piece tires will put a load on it. I just dont understand. maybe its just a v6 thing.
I don't think so? 36 inch tires and 4:56 gears and that much work done on motor, cam is 1400 to 5400 RPM so your in the power range... should really do better. Inline six jeeps do fine with that tire and gear on stock motors.
