As my car has evolved on its current build it's made

199bhp @ 18psi SCA (Fast Ford shootout about 2½ years ago)
248bhp @ 25psi at PTS (RSOC day 18 months ago)
256bhp @ 24psi at SCC (August 2006)

Have to agree with Christian and say 244bhp @ 18psi seems a smidge optimistic

File the DV in the spares drawer.
