His log seems ok for what he's doing. Not great, but not bad either.
Probably richen up the midrange slightly and lean out the top end, as well as smooth out the timing between the two extremes, and not have it start tapering up top.
I'd be curious to see a proper virtualdyno plot for this. I bet it makes torque lol

Hahaha! FM is about 6 hours' drive from me but I have another shop with a proper dyno much closer to me (Welcome to MAC Autosport) that let's me run whatever junk I show up with. I do plan on dynoing but maybe not with this turbo, I just ordered a bigger one.
I'm using the MSPNP 94/95 spark map with 1-2 degrees pulled out at the very top. I have a knock sensor det can setup that I need to install and then on the dyno I will add more timing. Timing is what broke my last motor so I'm going to go slow with it right now. Thanks for the tips 18psi. I would love it if this made 250hp but I don't think it's anywhere near that. I'll do a VD run next time I get a chance. Yes it makes torque, but I have to be careful I'm still 5-speeding.

Well I blew my turbo tonight :( I was doing some acceleration runs in preparation of doing a VD run and on the last one as soon as it hit 20psi I heard a super loud whistle from under the hood and lost power. No boost after that, though externally everything looked fine. The turbo was glowing nicely. Once I got back in the garage I pulled the air filter and there is about 1/4" or more shaft play and the car is blowing lots of smoke out the tailpipe. Was hoping to boost for America all weekend but I guess not. New turbo won't be delivered until next week. Once it cools down I will investigate further.
I did some more reading and tuned my engine states, and then did more reading and saw that the general consensus is to backdate to 1.4.1 so I did that. Runs great, idle is fantastic. Still no sync, and no rev limit for whatever reason. I'm pretty sure all my settings are correct, is this a pot or something I need to adjust on the board? Any help would be appreciated, maybe I can sort that out this weekend instead of boosting.

I tried to run that log through VD but it doesn't log RPMs past 3000 or so. Does anyone have any hints for my sync issue since upgrading to 1.4.1? Otherwise I will just revert back to 1.2.0. I accidentally revved to 7400rpm today since I have no rev limiter at the moment.
