are you guys running stock fuel pumps with 450's? if not what are you using?

 

walbro 255lph Intank. Dont use an inline, just use an intank and replace the stock pump. The stock pump is fine for low-med boost. Dont use an FMU

 

walbro, a good shop wont even tune your car without a high flow fuel pump.

 

upgrading is like insurance, not because you have to have it, but because its brand new and you know it wont fail,walbro 190 lph or 255 lph would be good, either one will do the trick, most people would say defenitly go 255, just cuz most think more is better, which isnt always true, in this case it wont matter, and i never heard of a shop prior to some dyno tuning ask 'hey you got a stock fuel pump? if so sorry take your $150 per hour somewhere else'......btw your stock pump will work fine if you need it to....

 

the 255 is overkill unless youre going for like 500hp... 190lph is just fine. Id rather upgrade first than either lean out due to finding the limit of the pump or having it fail altogether
