basically as the title states my car seems to leaning out on the top end. I knew something has been a little off on the car. During a WOT pull/ fun race I logged 726 timing at 4.2 degrees of knock. I know at WOT timing should be between 900-1000. During this run I went against one of my friends bone stock 99 Trans am, he won pretty convincingly. Granted this was a highway pull, not from a dig. I know it's not a accurate representation of our cars, but still should of been pretty even at least. 2 years ago the GN was dynoed at 300 WHP and 400 FtLb of torque to the wheels. Mods are Poston headers to THDP, RJC crossrflow exhaust. Manual boost controller, 39# injectors, SMC alky kit(single nozzle), believe it has a old school red Armstrong fuel pump(essentially a truck Fuel pump isn't it?), turbo tweak chip, fuel pump Hotwire kit, spark plugs and wires are not factory but cannot remember the info on them as they where on the car when I got it. Fuel filter is less than 5 years old(ac Delco). Ls1 MAF. I have the boost turned down to 18psi. Sure I am forgetting some stuff.
