How much boost are tunes pushing?

[Kairus]

Looking at dyno graphs from before and after just a tune, the numbers are impressive. Is a lot of the gain from added boost? How much boost are tuners pushing on the stock turbo?

The Steeda tune I have pushed the boost from 18 psi to 20 psi. The increase was about the same on the Focus ST I used to have too.

I have our target boost on my custom MAP tunes to 22psi on 93oct, and 20psi on 91oct.

 

[EcoSnake]

25.5psi average

What tune are you running, EcoSnake?

Yea that's pretty high. I know the LMS tune basically sticks to the stock boost levels

Anyone here experienced the IC hose to the turbo popping off with the added boost?

That's starting to seem like a common occurrence. Just tighten them down a bit.

Cobb 91 tune. I think they spiked mine.

22 on my Cobb custom.

The Cobb OTS would peak around 22 psi for me.

My cobb OTS hits around 25psi frequently.

My Unleashed tune is roughly 22-23 psi now that it can exhale a bit better than before.

Careful with this guys.... that seems very high. I haven't seen anywhere near that. With the OTS tune and now the MAP tune. 21.xx psi max.... Especially you EcoSnake on a 91oct. tune.

I had just posted on FB the other day on the ecoboost page where I blew my intercooler pipe off the turbo, running cobb canned tune, when I checked the other clamps with a ratchet wrench there was plenty of tightening to do.
