I want something that will keep boost at stock levels with the following mods: apexi intake, effini y-pipe, hks downpipe, and racing beat cat back. However, I would like said control method to be usefull later down the line as I continue to upgrade to a stock mount intercooler, then eventually to a power fc and a single turbo. I heard the apexi avc-r is a great boost control for upping the boost, but will it be suitable for locking in stock boost levels and preventing spiking? What about external waste gate use? Where would I put that thing, anyway? Or, if I can get the cash, should I just get the Power FC (key word being if on this one)? Yes, I am paranoid. I don't want to rely on the "three mod rule" or anything like that. I want to be sure my boost levels stay stock. I want to avoid pulling everything out just to port the stock waste gates if at all possible. Any suggestions or past experiences will be much appreciated. I don't want to shell out cash on a control method that will just become a paper weight on my work bench later as I continue to upgrade.

 

Profec B, at least the "spec 1", is really good for controlling the twins or a single turbo. On top of that, it's cheap.

 

That's the Greddy one, right? I took a look at it, but it seemed rather basic (not always a bad thing). If the AVC-R is capable of doing the same and more, I'll shell out the extra cash. I just don't know anyone who has used it on an almost stock set up. Thanks for the reply. I will consider the Profec B. Isn't it just a low or high boost switch? So I'm assuming low would keep it at stock boost level. I heard the major problem seems to be spiking at the transition between primary and secondary.

 

Do a search on Profec. I have the Profec B spec 1 on a mostly stock car and its fantastic. Its the best mod I've done since it allows me to drive the car safely w/o worrying about watching boost. I was not able to control boost and spikes very well relying solely on my Power FC.

Hoe that was helpfuel.

 

I have the avc-r and i love it, Ive have completely dialed up the boost transision.

not to mention the other cool stuff....the only thing about i dont like, the speed input dosent work most of the time, it just jumps all over the place, itsent accurate at all..but hey the main part works great

 

i got mine for 380 on ebay brand new

 

The power fc didn't help control boost well enough to get rid of spikes? Whoa. I thought that thing was the cure all for engine management issues. I'm trying to hold off on getting a pfc because of the price, and I've looked at the instructions and don't think I'll be able to tune it myself. I'll be moving to Chicago in a few months, so then I'll have a reputable shop nearby. Until then, I'm avoiding it.
