Camaro ss tsp vvt2 cam, slow throttle opening
So, i started working on the car today, its a 2016 SS auto, it has a jlt intake, air force intake manifold, stock throttle, long tube headers, catless xpipe, and a circle D 3200 rpm converter. I spent the day doing vve part throttle stuff until it was near perfect, then decided to give it a little wot and see what it would do, tps was not going over 50% and fueling was vey rich, i was expecting to need to add fuel up top.
well i went to the dyno and started jacking up VTT in 10% steps, at the beginning it seemed to help as i would get a couple off spots where it would actually go to 100% tps, after that didnt work i tried with the DD tables and it seemed to have no effect so i went back to stock torque tables and DD and finally got the throttle to open to 100% for most of the pass, from 2500rpm to 3500rpm it will ramp from 78% to 99%, how do i fix this?
This is the tune i ended up with, havent touched the timing tables except for vcp spark which i zeroed, cam timing is zeroed too as i was told by tsp that with the 0 degree phaser limiter i have the cam wont move.

At this point i am at 446whp which is pretty low since i had 469 without the cam, i will be back at the dyno tomorrow to finish up the tuning.
