2017 ZL1 tune. not having much luck

Ive been messing with my buddies 2017 zl1, car has 5,000miles on it bone stock. made 525rwhp on a dynopac running 91 octane.
I was trying to squeeze some more out of it, not much success. i was able to get about 5hp more up top but picked up 15hp from 3,000rpm to around 5,000 then it flat lined back to about factory hp then at 6200 it peaked up 5hp more. AFR was 11.5 across the pull.

was wonderng if some of you that have tuned these could check mine out and give me some pointers. thank you, Joe.
also attached a log from driving around today.

That AFR is rich... by on the right computer... but there is gains to be made

i Tried up to 12.5 and it picked up detonation.
When i pulled it at 12.5 it lost 20hp so i added it back

If that’s the case I would check to make sure WB is reading correctly... also differ AFR will put a different load and change timing possibly too... not saying that’s what happen but seen that many times before

im working with mine I have headers throttle body and flex sensor. on e50 the car is just stupid. at 60 mph its killing the tires so know its up quite a bit on power. Here is where I am at so can compare. Look at the little things I also did my torque model as my trans was shifting terrible and now better then stock. Just do a compare and see whats missing. I do have some throttle closures I need to address on it since raising the e85 model though. I have had no kr show up running .79-81 lambda but also have e50 in the tank. Been playing with cam changes and so far part throttle way better by advancing cam down low and removing some of that egr cam timing.

ok now looked at pull and its all over the torque limits as dumping boost and pulling timing. Use these channels to log next time on dyno and make a lot of the changes you see in my tune.

Cam timing is a cake walk on these platforms

Ben what do you recommend for the cam? I haven’t removed all the retard tapered about half. Seen others remove all of it below 3500 or leave a little in light throttle for cruise mpgs. Thank you.
