In the last month or so I've made some big changes to my car. Swapped 4l60 for t56, changed the rear diff and ratio, and did a cam swap with springs. Ive also had a heck of a time with my tuning equipment. My laptop's HD died and I lost most of my tune files and logs (should have backed them up), and my WB sensor crapped out. Now I have everything back in working order and Im having problems figuring out what is going on with my car. It a stock LQ4 with sloppy stage 2 cam, pac1218 springs, ls1 intake, ls1 rails, ls1 28lb injectors, walbro 450, 3/8 gas line, DIY 4 inch CAI with new filter. Before making the cam and trans changes I dailied the car and put almost 18k miles on it but always thought it kinda run like a turd for what it was. Now it still doesn't run how I expected it would. Ive been VE tuning with the wide band and noticed that the WOT areas of the graph haven't really changed since the cam swap, which I thought was strange because it should be pulling a lot more air into the cylinders. Ive also noticed that those areas of the table have always had a drop/leveling off what seemed out of place. injector duty cycle is only at 80% at WOT in 4th and my arfs are still a little rich at less than 12.5. The VCM scanner HP and torque numbers seem pretty low to me as well. What is going on here? The car idles and cruises fairly decent. I still have some occasional stalling on deceleration issues and a strange hesitation when fist taking off but overall it seems pretty drivable. Is there something that Im missing or any suggestions? Should I continue VE tuning, then MAF, timing, etc... or figure this out first.
