Again, why would load be different. Doesn't make any sense.

Like I said, post logs to show what you're talking about so we can fill this thread up with data. At least with bootmod3 there's no difference between gears. Boost, timing, and load are all the same. Load is primarily based on RPM and throttle angle, not gear.

That's what happened to me when I increased the boost timing retarded which resulted to lower top end power.

I learned that more boost not always equal more power, Ignition timing is the key, If we don't get a good combustion then the extra boost is useless.

Also how do you make your own tune ? I wish I could do that.
I was planning on tuning my own car but I'm going to wait until I can get dyno time for this very reason. It's typical to keep upping the boost and then add timing until it begins to knock, but you don't make the most power that way. You need to put it on a dyno to really tell if you're making more power with the changes you make.

I agree, our cars seem to like timing more that boost.
