No with wheel spin you cannot guarntee this
Can you do another log but only logging boost and RPM's in 4th, and try not to wheel spin, take it from as low revs as possible to as high up as you dare
 
MAF reading x 1.275 = BHP

So 175 x 1.275 = 223BHP

so wheel spin is causing you issues
Try and get another log and post it up and well see what that one says
 
Yup

Your boost and MAF figure don't match up
With 22 PSI of boost you should be getting 260BHP+

New tyres/better weather and try again

Wild Willy has done one of these out of bits and pieces, might be an idea to have a look at his one (in his readers rides section) as a template.
I'd be interested in one price dependant
