Hello,
I'm trying to find out more about the early overboosting of the V-1710s in the Allied service. One of the documents can be found at the Peril's P-40 web site, dated late 1942 (here). The excerpt from the Williams site (here) states, about the Mustang I:
Still there is many blanks left to fill, like the RAF CW use of the early P-40s in the N. Africa. Any further info is welcomed.

The Flying Tigers were also using overboosted engines, from 58" up to 62" Hg is claimed by the crew chief Frank Losonsky (in the Vees for Victory book).33. This aircraft is powered with the Allison 1710-39 engine having a rated power of 1150 H.P. at 3000 R.P.M. and 44" Hg. at 12,000 ft. The engine was originally equipped with an automatic boost control limiting the manifold pressure at the lower altitudes to 44". The British remove this so as to get the vastly increased performance at lower altitudes thru the judicious use of over-boost.
