Question Boost cut?

Howdy all,
I've had a search and read through and I'm fearly sure I've had boost cut.
I've recently had a major service and I noticed the mecanic turned my mbc right down, so I turned it back up a bit and now I'm getting the check engine light when I first start the car cold. Then it goes away, but has come on a few times on the highway now. I'm assuming its boost cut? My question is if you reset the ecu will this fix the problem?
Any help would be greatly appreciated.
Cheers!
-Trent

Do a search and read the CEL code of the light (assuming you are running stock ECU).

If you can't do that, take it down to your workshop of choice and have them read it.

Boost cut is like hitting a brick wall, not a CEL.

Yeah I will try checking the cel code tonight. I've been meaning to get a tune done anyway. Any suggestions on workshops that would do the tune and put in an ebc? Also any idea of cost as I'm pretty skint after x-mas?

What is "it"?
And do you have a FMIC or TMIC?
