Help with new tune and manual conversion

[Updog]

Just built this combo and tested on track, overall happy with the results however I know there is much more power to be had from this engine. I have converted from an auto (4l60E) to a six speed manual (T56), I am having an issue when the ABS is plugged in then it constantly flashes with low traction when ever you use the accelerator. Went on the dyno and produced 350 RWHP, I have done some looking into what I should get with this combo and was expecting another 100 or so hp from it. Any help would be appreciated details I have are as follows

Your fuel injector data is wrong. You said it has 440cc injectors, that roughly 41-42lb/hr but your tune file shows stock 30lb/hr injectors.

That's probably why your VE table looks so weird because you removed a bunch of fuel from it to work with those large injectors instead of having the right data in there.

Timing at full throttle seems low, only around 20ish.
