    So I called SplitSecond on Thursday and it turns out if you don't have the customer mdb file in the R4 directory where the EXE is, it has issues reading the file when you try to flash it in the newer Windows OSs. I put the file in the right directory and flashed it up and we're good to go.

    Went out to see if it was working and I'm not even hitting enough load to trigger it yet haha. I'll be adding in some WGDC to get my loads up and eventually get to tuning my 6th port.

    Exciting stuff!

    So after a bunch of testing, I finally have some PI spraying. The values in the map needed to be higher than I expected them to be to actually see a difference in AFRs. After getting a baseline map set up, I've adjusted my cals a little bit to even it out and I'll be working to dial in the extra fuel. The bat differences are wonderful too, went from 106* to 80*. Now that I'm not maxing out the injectors any more I can start increasing my wgdc and get some more boost up in this mofo. I'm hoping to have some real power soon!

    Big thanks to @Sho and VegaTuned for helping to answer all of my dumb PI questions.

    I've been dialing stuff in. Unfortunately I am only able to do a couple pulls each night and do a revision after those, so the process has been slower than I'd like it to be. This most recent revision was the first one that made me start laughing since I got the car back together. 20psi peak, 17.5 at redline (that'll be fixed soon).

    This is still on OTS timing and has plenty of room still. There's still room on my fueling as well. Once I get it to flow some more air I'll add some more fuel and get it richened up again and fix the cal. There's a bit of back and fourth to get the R4 and AT tunes working together, but it's really not that bad.

    After doing my pull, I needed to go get some gas, so I got on the onramp and had to pass a Camry that was driving like an asshole. I got on it in 2nd and immediately hit 20psi brapped all over the guy and rolled through 3rd. I really wasn't expecting it to hit as hard as it did. The guy must've thought I was a goddamn lunatic. It feels real good to be able to do that to dumbasses again though.

    The fiance's mom is in town this weekend, so I'm hoping I have lots of time to myself to get this shit really dialed in this weekend.

    I'm around 400tq now and I'm looking to push that out as far as possible. I'm thinking about starting around 350tq early on and ramping up to 400 or whatever I can get to up at redline. Still have a bunch of timing to add, so it's only going up from here. I have been holding off on doing any more pulls because the coolant line on top of my turbo is visibly blackened from the manifold heat cooking it. It's one of the high temp hoses, but the manifold temp will reach way higher than what that thing is rated for. I have a fiberglass heat wrap coming to fix that up and I also got some heat reflective tape for anything else I think might warrant it. Tomorrow I have a date with the race shop to get a little bracket fabbed up to fix my intake mounting, so I'll post that up once we get it all figured out.

    Had some issues with what I think is spark blowout during one of my more recent pulls. I'm around the same power level that I was before the build and I was having a similar thing happening during my pulls then too. Not really bucking or anything, but I can feel a brief stutter randomly during the pulls between 5k-redline. I'm using stock heat range NGKs gapped at .028", but from what I've read a lot of built guys are using a smaller gap. I bought a new set and gapped them at .020" and we'll see if this fixes that.

    I also got a new fuel line from Chris at Speed Solutions to replace one that was a bit too short. I had some Parker hose in there for the mean time, but it's not rated for ethanol and I don't want to risk that for any longer than I have to.

    I'm doing more tuning this weekend and I now have a deadline to finish this stuff up by.

    I'm planning on going to this and seeing how the car does. It'll be cool to really run it and see what it's made of. Lots of real crazy cars show up to this, so that'll be cool as well.

    Fun stuff!

    WGDC has been ramped up and it looks like I'm at the point where the TMIC is bottlenecking me. I've got a few more options at this point, so I'll get back to that a bit later.

    As far as the tune is concerned here is where I'm at currently:

    This is at 9* of timing at 6k, so there is a ton more to add still. The gains for each degree of timing has actually been pretty crazy, so I'm not sure where this is going to end up. It is feeling great though!

    On another note, the .020" gap fixed my blowout/stutter issues during pulls, so that's good.
