We do seem to have a disproportionate number of boost junkies in our little group! Seriously though, so rewarding. Great seeing the project yield its reward.

We call you our blowoff valve for a reason...

Vince @ RT got back to me this morning, I should be good to drive it around normally, he said not to WOT it to redline but otherwise my tune should be pretty close. I'm still a bit paranoid, so I'm not likely to do too much, but good to know he thinks I'm close.

JAR, just throwing out there if you start planning now, in 16-20 years you could enjoy boost as well!

One of us... one of us...

Something to think about. They called about my car today. Turns out my YouTube smoke machine and Amazon Boost tester were spot on. They found that my driver side flange for the header has an exhaust leak. Which explains the low boost and the AFRs being a bit whacky. I talked to Switchback Racing and I'm gonna convert the flange to Vband. 3rd time this thing has happened on that side. Last time he flattened the flange when he repaired the flex joint. I'm thinking vband will cut that problem and make removal 100 times easier in the future.

Thoughts?

I really like the idea of the V band, especially since you've had a few issues on that side. But from a QA perspective, it sounds to me like your mating surfaces are warped slightly, and not matching or exerting even pressure on the gasket, which is why there have been multiple problems in the same place. Converting it to allow for "pipe docking" as BettyZ describes it so perfectly might solve the issue for good.

The first two times I had no clue, the last time it was confirmed it was warped. But I look at this as an opportunity to make working on the car easier and killing the warped flange issue for good.

Tune completed late yesterday evening. I was using the 7.5 psi spring, looks like I maxed that out. RT Tuning is practicing social distancing, so I didn't get a chance to talk with Vince (tuner) directly, and I'll reach out to him later today. Basically I want to find out if I ran out of spring pressure first (likely) or fuel capability first.

Time to drive and enjoy the car for a while!

Future plans:
1) Hook up my boost gauge. I just need some time to pull my upper plenum and tap another port.
2) Driver mod. I'd like to take some classes and enjoy some track time.
3) Likely go to a larger spring at some point, and pair that with a boost solenoid.
5) Better wheels. OEM are fine for now, but since I've got the power, now I'll play with the looks a bit.
6) Eventually suspension. I'm coming up on 64k miles on the car, so it's not an immediate need, but soon.
7) Depending on what the summer shows, possibly some of the track spec hood vents.
