Just like the title says, ever since the exhaust was installed, at WOT, it seems harder to hit boost target (15 psi) now versus on the stock system........?

At least according to my boost gauge it's now only hitting 13.5-14 psi and it should be close to 15 psi. Before the exhaust I was hitting 15+ psi at WOT consistently.

Has anyone experienced this? Is it all in my head regardless of what the boost gauge says?

Does power feel the same?.. if so, no worries less boost/stress on the turbo's is a good thing..

Not for me, my pre-boost and target are almost right on top of one another when logging, and I'm completely catless

I'm not sure, and that's because with the added "bass" from my exhaust, it sounds and feels fast, but just don't know if it's "faster." So that's why I go by my boost gauge......LOL.

In theory, wouldn't it boost a little less due to less back pressure? Like someone had mentioned, the turbos work less hard to obtain the same performance?

But then I thought again, if the boost target is set at 15psi, should it hit that or get very close no matter if the exhaust is catless or stock?

Maybe that's what I need to do........data log.

With the procede you should hit the boost target, I never fail to hit mine even with upgraded turbos...being catless you should get there faster. Reset the adaptations on your command center and see if that solves your problem. I think they are mode 3, 12--->1 in that order, then reset the procede from the user software and see if that solves your problem.

K thanks, I'll reset those and see if it makes a difference....

[cstmx_ryder]

Resetting the procede seem to help a little.....but I just loaded the DIC beta map so I have to see how that works too.....

So I found out that the vented gauge reading was wayyy off from what the in-dash boost gauge says.

I mean, I knew the vented gauge was not as accurate as the CANbus one from procede, but it was off by a landslide!

In-dash reads: 13 psi

Vent gauge reads: 4.6 psi

I also calibrated the vented gauge after my exhaust install.....
