Looking for some advice from some 96-98 KB 2.1 owners. I bought the car modded and the previous owner bought it that way as well and didn't know too much detail. I know it has a forged bottom end, 2" pulley, JLT intake, stock manifolds, no cats, 39lb injectors, boost a pump, boost a spark, 3.73 gears. Came with a walbro pump but not installed so I'm assuming stock fuel pump. Also has a snow meth injection kit installed and hooked up but not turned on. I've only ripped on it a few times because it's making a lot of boost and I'm not sure if this is right. Here's a 3rd gear pull on a cool dry day. Is the boost supposed to creep this high? The Dyno sheet that came with the car it was only making 9-10 psi but from the date that was before the built bottom end and not sure about the meth. Any advice would be appreciated.
