Default Critique my ignition timing map

This is only the 3rd car I've tuned, I'm using a detcan but haven't actually loaded this map yet. I was using a much more conservative map to start. Just wanted to get some feed back and see what more experienced people think and where I can improve.

8.6:1 Arias pistons & Manley rods
Mildly ported bp head
94 oct fuel
90 degree F AIT, it's cool outside right now
Evo 3 16g on a home made log mani
Tial 38mm EWG
running 240kpa, boost cut set at 246kpa

If you aren't running e85, you are in risky territory at 240kpa.

Go look at this guys thread and take a close look at his pistons. See if you can spot the problem.

His thread is what prompted me to make this one. Here is the map I am currently using in the car.

So I loaded up the first map there but dropped top end timing to 16 degrees. Put the detcans on and hit the highway, still no knocking but wow is that a big difference. It pulls hard. Will likely leave it this way until it warms up here, then check again.

Looks like a Rev basemap down low. Much gains to be had with cruise and part throttle.

Good eye, it's a Rev built ms3 mini. I haven't touched anything under 110kpa yet.
