Scary VE area

Even if I tied my bypass open I would be in boost at 5000 RPM with the throttle applied. You are showing almost idle vacuum at that RPM. Did you confirm that you are logging SAE.MAP as opposed to GM.MAP? (At least that's what they are called in EFILIVE) You must have been logging it before to see 159 kPa.

Would our different cam profiles your stock (I think) and my GT7 account for different behaviors?
There is only one "PID" available with HPT for the 2 bar MAP. Here is a snapshot of same sensor , PID arrangement under boost. Hits 158 KPA. Haven't gone into boost too much since 2bar for obvious reasons. You can see the knock in this one.

OK, I take that back. I am able to keep out of boost if I hold 1st and take it easy on the pedal. Maybe not as low as 50 kPa, but I stayed out of boost. I guess I usually have the pedal to the floor when I'm at 5000 RPM.
The motor still has to be getting a lot of air though with the Radix spinning that high. So it's going to need quite a bit of fuel. I would bump up the entire higher RPM part of the table then use the AutoVE process to bring it down where it is too high rather than the other way around. A lot safer to be rich rather than lean. Did you bump up the entire stock table before starting?

I'll post up the VE screen shot when I get something that I want to start with.
Thanks for the input.

can you duplicate this crazy lean kpa area? me and dewey had a problem with my scanner the other day where it just went crazy with all kinds of weird readings. it said i was at 70kpa at idle. just a thought, maybe just a scanner glitch? after what i've seen with hpt's i believe anything is possible.
