Called procharger to order the pump kit and they asked if I had a 2003 silverado with DBW stock pump flows better than previous models. There procharger kit for that specific 2003 DBW application dosent bring a pump. So I asked and they said, that year the stock fuel pump is much better and dosent require it??? True or not?

Yeah I guess I should. Funny you started with fuel pump the truck is running with the procharger and your now getting the WB and boost gauge hahahahaha I did it the other way WB-Boost,install procharger then fuel pump.

 

LOL yah I do things bass ackwards some times, I looked at it like put the blower on, didn't care bout the boost, as long as it worked, knew I wouldn't beat on it till I had the tune close. So I wouldn't have to worry about how much boost I was running, since I wasn't beating the hell out of it I wouldn't have to really worry about it leaning out, so now that I have a good base tune and pump, now I get to see what its boosting and, where the fuel is.. Also I never planned on FI so it was like a spur of the moment thing, so never really needed the gauges. Wow wah a mouth full LOL

Get a pump
