I'm about to buy a boost controller and just wanting yalls opinions. i'm currently non seqential but plan on going single in the next few months so i'm gonna be needing one anyways and might as well get one now and play with the twins.

 

Greddy Profec B

 

Please use the search function, there's so many good posts about this already.

My 2 cents is the original Profec B (not Spec II). It's dead simple to set-up and use and just plain works. If you want fancier features, step up to the AVC-R or the Blitz or HKS units.

 

 

Profec B

 

Most reliable = manual

 

Hahaha....more like most likely to spike boost!

 

Erm ok.. that would depend on the type.. not all manual ones suck FYI. Lots of people use them.

I spent $500 for an HKS EVC that worked for a year before the solenoid crapped out. HKS wouldn't warranty it, and for the VERY few times I actually NEEDED to change boost while driving, it was hard to justify that outrageous price. $125 for a manual was a much better deal, and is less likely to go bad.

 

No, I don't know your boost controller personally ...but I do know many people who've used manual boost controllers and when the air temp drops they spike.

 

I've had my Profec for 4 yrs know with no problems.

 

I would attribute that to a crappy boost controller than. However, not all manual controllers have those problems. I have had no such issue with mine, and therefore would recommend considering a manual boost controller.

 

Profec B spec 1's are simple, easy to install, and easy to adjust. Do a search and see how many people swear by them.

 

Well...to you and anybody else willing to take the risk of a manual boost controller....Have fun rebuilding when ya spike!

 

that would be like me saying "Well...to you and anybody else willing to take the risk of a electronic boost controller....Have fun rebuilding when ya spike when your solenoid goes bad! "

 

Haha....

 

I have used a "Home Depot" manual boost controller for more than a year and have experienced no spiking. I won't say that it is the best boost controller out there. But, for $5, this Cheap Bastard is very happy with it.

 

As long as you don't get a piece of junk MBC they can work fine. For example I would have no worries about say, a TurboXS MBC spiking boost.

The only thing to worry about with one of those is is if you drive up to a much higher altitude than the altitude at which the controller was set. But otherwise it should hold boost just fine.

i'm taking out my daws device mbc in favor of a profec b because the temp does effect my boost level. temps never cause my boost to spike, but when it gets colder, i get more boost and run into fuel cut and then have to open the hood and adjust. i just like knowing that if i set the profec to 10psi that i'm going to get 10 psi, no less, no more, no matter what the temp, humidity, etc. that being said, if you're on a budget, a mbc can be very effective. i will say that the home depot controller is junk imo and you're better off spending $50 on a good mbc than spending the $20 in materials the h.d. controller will cost.

 

I have a profec b. Works perfect, no spiking with my non sequential setup. Nice to be able to switch between 3 boost settings and much easier to adjust boost compared to a mbc.

The Apexi PFC will control boost. Get the high boost kit
