AIR SUPPLY

i just put air bags into my 95 s10 and finished them up and was disapointed that i flip like 3 swithces and the damn air compressor flips on and it takes forever. how can i fix this should i get a bigger tank or a better compressor or maybe a higher pressure switch. there already does not seem to be enough pressure to lift my front end i have a 145 psi switch and a 6cyl truck. so any help would be appreciatedthanks
