Looking at your other log, the rpm of the values makes sense, since 2900 is right when you hit max boost and after 4500 boost is plummeting, so making peak HP right around where HP and TQ cross makes sense. I would need to look at another stock turbo PWG log but your boost does seem to drop pretty dramatically. I know it usually does, just not sure if to the same extent.

Your timing is great. I assume you have high ethanol content because your HPFP is dipping by up to 500psi basically the entire time until boost starts to fall off.
No I didn't. I should have but totally forgot about it till afterwards.

I'm hoping other PWG owners can chime in and give some perspective as I don't know what standard boost drop looks like.

Using your calculator and working with consistent E content for both 91 and E85, I've been doing E30 mix.

I'll do some logs tonight on the way home from work and see how it compares to this log I just posted.
