I was tinkering around with the Wrangler this weekend(and every weekend lol) replacing the motor mounts. I pulled the airbox to make it easier and had to slap my forehead. When I got it, I slapped a 4.0 TB on it and removed the hourglass restriction in the upper hose...the bottom tube was missing so I figured they'd already got that one. NOPE! OMG...Here I've been kicking it for not having the same feel as my 91 which I'd done the same thing to and it was my fault all along. DOH!!!
