That looks really good, the power curve looks nice and flat, doesn't taper off!

The smoke comment is funny - that probably appears smoke free on the road - that doesn't look like much smoke, sitting stationary it's not being distributed across a stretch of road.

Don't get hung up over the numbers - if you hit a few different dynos, every one will read differently. If you want to see 220hp, go visit a dynojet ;)

Flat at 930 deg ..not good. Must remove diag. limit to see above 930
You log too many useless things.
Do Boost, EGT , IQ
from IQ you can clearly see when power is being reduced to lower egt, depends on how it was set.

Also rail seems very unstable and that doesnt help.

Thanks Mac, I'll log IQ next time.

Rail pressure is really good till it hits 930°C, then it has a hiccup. Look at all tabs of the log. Ignore the first one and look at the next two tabs.

Lower boost to 28psi probably isn't helping EGT's either.

Lots of fun and neat to see that there is room for improvements.

Rail definitely needs some work, preliminary tune though, was having surge issues down low on a standard stage 3 so just wanted to make sure the turbo was safe first. Yes it still has EGT limiters, they're just set less aggressively at the customers request. Can adjust how hard it kicks in and when, and when it starts to taper fuel. Good point on diag limit, a lot of software we'd like to release, just have to do it all at once in large batches.

Can't wait to see what it does with cams :)

Would love to fiddle with this thing some more, but I couldn't ask Malone to waste time on it when I should have a 2260 to dial in shortly.

This turbo will be going to Francisco Garcia in Guadalajara soon. Really great piece of equipment. Really fast spool. Definitely have some lag now with the 2260vklr.
