MBC questions. Options

Alright Im new to the turbo scene and Im exploring the possibility of increasing my performance, and am currently on a tight budget. I was hoping to have sometihng for spring time, I was looking into a boost controller and obviously I cant spend 800CND on a EBC, so I was searching around the mr2 forums and they were talking about just using the ebay mbc's, they are only like 12 bucks which seems to good to be true but at the same time its not like a mbc is all that complex.

So anyone ever purchased something similar? And please spare me the "get what you pay for", Im more or less more concerned with safety rather then it working or not. Is there any advantage to buying a more expensive product other then it looking better?

Ya that is a consideration but basically what Im thinking about doing is have the boost set to 15 psi all the time, from what Ive read its safe for the engine and is no more harmful then have boost set too 8psi all the time. Which leads to my next issue. Fuel cut, I just got done reading about making my own FCD and I was having a problem understanding a few things.

After reading that page I have a few questions:

He talks about setting the ohm value between t1 and t2 according to the chart below, and doing so before installation, Is that value being changed using the pot? and if so why is there a need to set up the pot do read out 4.4v when installing? Or is there more then 1 ajustable screw on the pot?

So basically what Im getting out of it, is I set my initial fuel cut value of 15psi when Im done construting it, then when installing configuring the fcd to the stock fc voltage. Im just having trouble understanding how to set that ohm value?
