How to modify ddp?

[shaeff]

Unplug your manual boost controller, and see if it boosts correctly. I think the problem is more related to the reinstallation of the head than the ddp install.

just make sure you plug the vaccuum line back into the wastegate actuator. that would be very bad!

DDP works flawlessly for me, too.

I took my mbc off today and took it for a test drive and it's still the same thing. It boosts to like 18 psi quick, which is a good thing, but if I don't let off the throttle it will stutter. I guess it just means I'm hitting fuel cut, but it feels different than before when I was hitting it before the lexus afm swap. Would anyone suggest an electronic bc or just go with the maft pro? Thanks.

Turbo xs boost controllers aren't usually recommended as I have been told. My performance shop say they don't hold boost well and people usually end up throwing them out. I only asked if it had a light spring feature because those boost controllers are only suggested to hold only about 5 psi over stock boost.

ok to my first comment scratch that do you have fuel pressure? my home boy had a similar problem we woud floor it but it reach bout 5500 and start to stutter all the way through the gears and at certain speeds like 125 i would want to cut off. fuel pressure buddy check that.


just trying to help even if my 2 cent's ain't worth nothing.

Thanks for your help Boss. Every suggestion is duly noted and processed. All I have is the stock fuel pressure regulator so I can't tell you how much fuel pressure I have. I may order one from HPF since I have a couple of items to return.................lol
