Boost Controller Question
If my car is intially set for 6 lbs of boost and I add more boost, can a boost controller have a preset setting of only 3 lbs boost setting (for certain desired situations) which is less boost than the original configuration?

Re: Boost Controller Question (MARK's_C5TT)
I do not think so. My default is what LPE set originally and with my controller OFF that is where my boost goes. I think it has to do with the mechanical linkage at the turbo controlling the wastegate. The controller can only add boost or delay wastegate opening but can never go below the mechanical preset default. If you were to change the mechanical linkage at the turbo then you could use a lower default hence have the controller set to 3psi or whatever lower setting you desire. Mark, are you going to be a bad boy and void your LPE warranty?

Re: Boost Controller Question (MARK's_C5TT)
Mark, I am going to give you a little tip. I feel boost controllers are a waste of money. And I wiil tell why I think so. Unless you have a fast system or something like that you will have to tune for high boost. When you run lower it will be PIG rich...............sounds cool though. Unless high boost with race gas. I might be wrong, but that is my take on it. And yes you can set a 3 lb's if you wish. I was told you could .

You will not be able to set the boost lower than the wastegate/wastegate spring will allow, boost controller or otherwise. For example, I have a 10.25 lb spring (more like 9.5lbs). No matter what I set the boost controller to, my boost wont go lower than 9.5 lbs.

Re: Boost Controller Question (Earl H)
:iagree: He's right. You can only go as low as the waste gate actuator will allow ... but ... there always a but ... you can get lower psi actuators. Go to any good tubo shop (TEC, Majestic Turbo ...) they can make one in any boost setting you want. To test you stock one I use a bike pump and hook up a vac hose to it, "t" in a boost gauge and hook it to the actuator. Pump it and see when it opens. You can also tweek the one you have taking the arm off the wastegate and turning it a few times (spin it). It allows for a 1-2 psi either way depending on the actuator and the amount of adjusting that has already been done. Be sure to check it to find out what it's new opening psi is. Also you'll want to do both sides ;) Then you can set your controler higher for spirited driving :)

Re: Boost Controller Question (BlackSun!)
I have the hks controller. I was told you had to have lower spring to change to a lower/higher boost. I am just saying your tune is going to be off some where, on the A/F. I just leave mine on 7lb and hold on.

Re: Boost Controller Question (BlackSun!)
I beleive LPE uses HKS controllers. They are better for controlling boost spikes from some research I did. Gary isn't that whats on yours??

Wouldn't it be nice to have a baseline of Zero boost? I noticed on the the HKS Controllers (I'm sure others have it too), a code can be entered so that boost cannot be changed. If you have a baseline of 0, when you take it to the dealer, they can't use any boost :lol: :lol: :lol:

Re: Boost Controller Question (MARK's_C5TT)
Mark I am almost sure a boost a pump will not do what you want it to do. If it does let me know I have new one I bought for my mustang many years ago. :cheers:
