Were gonna see if we can tune it down enough with the 2 pumps always running, but if not im gonna turn the second pump on thru MS at 8psi. Gotta get some tires now tho. It wont hold the power its putting down now. Cant wait to turn it on up and get some real power. Already claimed a 03 Zo6 and a 469hp evo 9, i was only running 10psi and having to roll in it easy to keep from spinning.

 

Im just gonna make a suggestion, 2 pumps and a hobbs switch is 3 componets that may go out vs one pump....I realize your dealing with what you have but i would get it running like it is and put your pumps up for sale with em on the truck to see if you can get any return on investment, i also did this in the beginning and ill guarentee ya you will want to run more boost in the long run.... Magnafuel pumps are pretty damn nice too but for the price of a A1000 its hard to beat, but if your satisfied with your power level with 2 pumps just keep what you got : ]
