P-30 low on power greg 3-14-03  
1993 p-30 32 ft ambassador pinnacle motor home 454 engine aod transmission 33,000 miles doesnt burn oil runs perfect,smooth but has very low power going up hills if i am towing a 1994 ford aerostar my speeds will drop to 30-35 mph up grades has fuel injection looks like a carb but isnt. what type of changes could i make to increase hp or is there something i should look for

You might try using higher octane fuel if it is spark knocking. I've got a K and N air filter on my 1987 P-30 Winnebago and that seems to help it make more power.
If you've got an automatic overdrive tranny, be sure to lock out the OD.
Fuel treatment can help clean clogged injectors if that is the problem.
You may also want to have the timing checked to see if is within specs.
But powering that 32 footer and towing a mid size van is a lot to ask of a 454.
Good Luck.

I put a gear vendors over/under drive on my motorhome to help with the hills when I am towing. It works great. I also recommend an Amsoil air filter. It is oiled two stage foam instead of cotton gauze on the K&N. The Amsoil filter will flow just as much air as a K&N, but filters the air much better. Good luck
