Hp estimate....

Curious if anyone has done various modifications to early 12 valves and kept track on a dyno.
I have a 93 that I installed in a motorhome paired with a allison 5 speed, 4 inch exhaust, 3200 rpm spring, 10 psi fuel supply, fuel pin, fuel screw turned in, 12cm non wastegate exhaust housing, big air filter and run 28 psi boost...
On a side note, switching from a 16cm to a 12cm housing dropped my egts 200 degrees and I gained almost 4psi of boost and much faster spool up.
My last trip down baja, towing a trailer and around 24,000 lbs combined weight I was getting 11 mpg at 65.
Any guesses what my hp might be.
