Ok well reading thru MSEFI.com I came across a few threads that gave information on using volvo and GM Solenoids. Seemed like they were sucessful in open loop mode only. Not much mention was given on the success or failure during closed loop. I think a few of you have been successful in running your cars in open loop all the time. (hopefully im not getting myself turned backwards here) Seems like it was a coding issue in certain code version of MStune. Maybe some of you guys that have been making progess with the MS can help me out here. ( I really need to d/l mstune and play with the software)

This thread was quite informative but I must admit some posts were a little out of my understanding. Maybe if i was in the situation myself I would understand better what they are referring to.

Would I be better off getting a seperate electronic b/c and use that completely outside of MS? Would the use of a standard manual boost controller be sufficient? Im just looking for some options that would prevent me from spending 250-300 on a greddy b/c.

If you need something quickly, I'd stick with a cheap manual boost controller, either a Hallman or a Joe P. It will provide just about the same funcunality as the expensive name brand electronic ones. The expensive ones are nice, but you will get ripped off unless you are able to get one for less than $150 or so. I've taken apart my old Blitz EVC (before it got stolen) and GReddy Profec B apart and I looked at all of the components and the thing is not worth nearly $419 (MachV) or $349 (Boostcontroller.com)

For the MS, I haven't really done anything at all with my setup since my car is down because my sister broke my passanger side motor mount (long story)

But if you have a MS, give the boost controlling code a try. Like anything else with the MS, you have to be very careful because with 1 screw up you can damage your engine.
