I agree, the boost gauges are never 100% accurate. I had a PLX boost sensor on my car when I had my PLX gauge setup. It worked well. My only gripe was that it only showed boost OR vacuum, not both. Maybe they have fixed that by now. If you are planning on running an electronic boost controller, that can serve as a boost gauge as well.

Yeah not saying they're all off, but they can be. I'll keep an eye out for deals but I like the idea of having it all on screen and not having to mount a gauge somewhere :tup:

Will do ;) Although it would likely need to be tweaked a bit for your setup. Based on your peak torque number (race tune), I'm calculating a VE of 185% for you :icon14:

Glad the boost sensor worked well for you. I'll be running it through Dash Command on AppRadio which has customizable gauges. They show vacuum and boost on the same gauge :tup:

Alex at Motion Lab came through and is going to have a manual boost controller waiting for me when I arrive for the tune tomorrow :tup:

This whole time I never realized you were in NC lol. Motion lab is awesome and tuned my supercharger and turbo setup. If I'm free I might drive up there to check it out.

:rofl2: Yeah man swing on by if you have time. I'll be there at 10:30 and I'm guessing the tuning will start around 11:30.

I just went out and played with dash command a little. You can definitely dial in the boost readings by adjusting the VE. I settled on 99% for now. That was showing a peak of 8.1 psi during a pull in 3rd gear. I still wasn't full throttle so I'll probably need to play with it some more but I just wanted to kind of prove that it can be dialed in.

Lets see how much a comedian he is when we meet one day and I guarantee you I will be the only one laughing.

Easy fella.

Anyways, I figured out that rattle. My h-pipe was knocking against the crossmember. I couldn't get the exhaust adjusted any higher so I used some washers on the crossmember to get some more clearance. Took it for a spin and that solved it :tup:

Puckshaw did you think about move up the rev limiter by the tune? I know some guys set it higher (8k RPM) with NA but do not know if it is safe with FI setups.

It's not safe with NA or FI applications. The guys running 8k redlines are asking for trouble. The oil pump will beat itself to death. Its internals are crappy sintered metal and they will come apart at high rpm.

I've heard the same about the oil pump. I don't see any need to chance it.

Whenever I build a motor, I'll throw in the Nismo oil pump with billet internals and rev the hell out of the thing. Until then, no way.

How did the tune go?

post the dyno results also if you can.

I keep hearing great things about Motion Lab.

Getting a late start. Fed Ex was way late on delivering the boost controller. I'll post up when we have some results :tup:

Well we ran into a fueling issue as we crossed into the 500whp range. The shop and Sasha seem to agree that the pump isn't getting enough voltage so a relay will probably need to be installed. I pulled the pump to make sure all the hoses were good just to rule that out and everything appears to be fine. The shop is pretty booked up until after the holidays so I'm not sure if I'll be able to get this straightened out until January.
