Adjustable Elec. Boost Controller.....why!? ---

[alwayscode390]

I am sorry but I am not understanding why people put boost controllers into their trucks.

If I have an ultimate chip and a 3 bar I can go to 21lbs of boost right.....so if I want MORE boost, is that when I want an electronic adj boost controller (like 25lbs)?! I just dont see why people would want to regulate their boost to lower numbers than the maximum available for your tune?!

I plan on using an ultimate chip, pte63, a/a intercooler, atr headers, atr 3" dp, ProGate ext wastegate, and a vortec BOV....will I need a boost controller for my build, or should I leave that up to my tuner after I get a rebuild? Thanks ---

the stock boost soleniod is marginal at best....i would'nt want my 7-10k engine depending on the stock solenoid the control boost spikes and/or overboost. :2cents:

x2 i would definitely not run 25 lbs thru the stock solenoid.
you can get a greddy or other type stand alone units that have a bunch of neat features.

I've done it for years. If it's programmed properly, it can work better than an aftermarket controller.

To answer the original poster's question...

Most ultimates don't work as they should out of the box... 17 psi setting really isn't, boost control is choppy, etc. This is mostly because there are so many turbo/intake/TC/exhaust/fuel combinations out there that you couldn't possibly set up the attibutes to cover them all.

They can be (and have been) programmed to behave as they should. And, you can set the programs up such that if you do happen to go over the target boost, the chip can respond with more fuel and less timing to limit the damage.

I believe what Dig says, however, I also have a Greddy Profec II and have to say i love it. Even though its kinda hard to figure out, it really is a great tool. The thing I like about, is that you can program it to stay at whatedver boost you wnat through the entire run. If you ever watch the stock boost on DM, youll see it fluctuate with RPM and shifts. The Profec, gives me a totaly solid line all the way down the track. + side is that you dont have to open a laptop for it. - side is that it can be confusing at first.
