The first time I did the MOSFET mod to a 148, it worked spot on. ExitThirteen has a thread here if you search for it that makes it very easy to do. At 3.85v from a preset bias, it gets about ~24w out.

These MOSFETs are supposed to be most efficient @ 4v; but that is hearsay. But 4.1v is pushing it a bit much even with a heatsink. Best set at 4v or slightly less. I see 30w with a single MOSFET in a Galaxy after the tx coils are peaked; 50w should be seen in two unless everything isn't right. 60w is the breaking point.
