Stock turbo, stock engine, 750DW injectors, 340 pump, tgv and evap deletes, ETS top mount. ON e85. I have it hitting 22 psi but want to add more power with timing and fueling, does anyone think they can help me, dyno video, log and Rom with defs are in the link to the zip folder. Rom I used has a patch on it so just put the defs I have in the zip folder in your meta. Anyone who can edit this rom to have a bit more power or can give me some advice for it would be greatly appreciated.

in your log i can't see
target boost
wideband reading
ignition total timing
fuel final base (primary open loop map enrichment isn't the same)
you've also logged the manifold relative pressure that caps at 18.5psi, switch to the absolute or direct manifold pressure to get the full range of it.

- also doesn't look like you have fast polling enabled which would really let you get a better look at what's going on.

Your injector duty is already hitting 105% so unless you can lean out the lambda reading you're not going to be able to add any more boost in. What i would be concerned about is you've got some feedback knock on the start of the pull, to make it actually knock on e85 is some job - have a look round the engine bay for anything that could be rattling/jingling and triggering the knock sensor.

Once your logs are better and you've a clear picture of what's going on then it will be easier to say where you might get some gains. For e85 though that's going to be more dyno time and a lot of runs with timing adjustment to see what works best for the car.

wideband is the afr sensor one, I have it connected in a not typical way. I think the knock is ghost knock as well
