NOS/ 100 shot... high volume fuel pump needed?

[QWIKVIC]

Hi, I'm running a direct port NOS nozzle kit with 100 shot jets and I was wondering if this set-up would require a high volume fuel pump?? I have used it and barely eperienced any spark knock but i still fear that it may be running too lean. Also, does anyone have a recomendation of where I can get a "flip ship" that is specifically programmed to my application? Thanks.

I would definitely recommend you get a larger fuel pump. Don't take any chances when it comes to your fuel system. You may contact one the SCT guys here on the board and see if you can get a tune through one of their dealers.

The kit was made for the stock pump but it is always good to upgrade . I used the stock pump all summer with a 100 shot and no and no trouble . I just put a 255 in because I'm going to be using a 150 shot this summer .

Where'd you get the 255 from? Is it an in-tank pump?
