BP kit folks. Question on wastegate plumbing.

Florida to Mexico and back to tune? I'm sure you can rent a dyno for less and get more consistent results.

Get real

Not to be rude but you're out of your depth. Seriously.

For clarity and to expand your insight "Mexico" is a euphemism for an out of the way place free of traffic and relatively safe to do things that wouldn't be reasonable or prudent in a congested area or your neighborhood. Tuning an EBC for gain requires wide open throttle runs under load in search of boost drop off at higher rpm. When it's detected you adjust the gain in 1-2% increments and repeat the process until surge. When you get surge you back off the gain until the desired result is achieved. Don't get it twisted I'm new to this but this is the basic concept. And for the record IMO "tuning" on the road is a better tune than a dyno tune for driving. I experienced that with my Titan when I went from full bolt to Jim Wolfe cams. Had to add all this because I don't want to come off as an a$$ and my intent isn't misconstrued.

I'm currently having this overboosting problem! With ebc off I hit as high as 13.6 @ WOT, low boost setting is at 9.5 I hit 10.6. (I have the 8 psi springs that the installation booklet recommended to install)

Install is the 7.5 Yellow spring and it seems pretty consistent at least in my case that the guage reads 1.5-2psi over the isntalled spring rate. It's done this on me with the 5lb,7lb and the 10lb springs. But my previous problem had several causes and one of them was a small hole in the passenger side wastegate. While troubleshooting all my runs were done on wastegate only. with only the lower wastegates plumbed and the upper open to atmosphere. It only overboosted until I re did all the vacuum lines. After replacing them all the 5lb spring hit 7.7psi consistently. After I got that under control I plumbed the EBC with new vacuum lines. Whatever you do stay out of it until you get past this bump. Piston Glitter looks like artwork but it hurts your heart.
