ok im sure this hase been brought up in the past but i cant get the exact answer im looking for so here goes again,

ive got industrial injection 60hp injectors in my truck no other mods other then no muffler my truck has 194,000 miles, i kno my truck is running light on railpreassure due to the injectors, now im looking to upgrade my pump i was going to order the arson 3 today but im guessing shane at motorsports is closed due to the holidays but after further reasurch im thinking that the arson3 wont do me any good due to the milage i have on the pump, i called the guys at diesel auto power and they can get me an industrial injection modded 33% over cp3 for $1,050.00 id pefer to spend the 400 for the arson rather then buy a whole new pump. shane and other people told me the arson will wake my truck up even without a tuner but d.a.p says it wont n neather will the new cp3. should i just hold off n save to get the new bigger pump or just go with the arson3 to put on my stock one (keep in mind i plan to change the turbo to a 62mm or bigger and run a smarty tnt or mabe an h&s)
