Boost cut?

[nynhex]

As with the 1st gens, we also suffer from boost cut. I'm wondering if anyone has done anything to combat this?

I'm thinking of looking into the ATP boost cut defender and a JoeP or Hallman manual boost controller so I can hit/hold at 17-18PSI.

If anyone has this or a similar setup, please post it up. Hitting 5k then watching the boost go bye bye sucks.

I may take you up on this. Just trying to see how/if it'll work on the 2010. Probably a good idea to get a boost gauge. Any that you recommend?

I'm gonna purchase a Hallman Boost controller, I'm just as sick as you watching the boost cut

I'll probably end up going with a Hallman or a TurbsmartXS MBC. While you're at it to be on the safe side, I'd probably go ahead and move towards PTP pump internals and an ATP Boost Cut Defender.

That combo should keep you safe and solid at 18PSI.

Can you explain boost cut to me. Sorry, I am guessing that you are talking about the boost limitation in 1st and 2nd gear. but Any info is good info in my book.

The limitation of boost in 1st/2nd is not an ECU issue, rather a load issue. Typically it's hard to generate enough progressive load to hit full boost.

The boost cut I'm referring to is the factory "choke" point. If you notice you rarely hit 17-18psi besides spikes. I'd like to be able to hit/hold 18psi (safely) so I'm doing some research on the best way to do that. At 18psi the fuel pump is maxed out and we hit fuel cut. This is bad.

What I'm trying to do is control the boost and keep it steady at 18PSI, not let the AFRs go nuts, supply enough fuel, and not blow up.

So far my thoughts are using an ATP Boost Cut Defender, Manual boost controller, and a CP-E fuel pump. I've read some nightmares about the PTP, so I'm going to steer clear for now.

just wanna let you know i've heard some bad stories about using ther internals kit as well it's better to stick with the cp-e pump

I've heard the same story using the internals or full pump. I've yet to hear a problem with CP-E. Way more expensive but worth it, IMO.

Why not get a map clamp and a boost controller?

And what have you heard? I've been running PTP's internals for over 20k miles, along with several others in the area.

Man turbos are ridiculous. I love my supercharger! I hate constantly trying to find my boost on the Speed3.
