Fuel injectors.
The current fuel injectors I have are 19lb. I was thinking of 24lb as the next perfomance upgrade with the mass air meter. My question is will I need a bigger fuel pump, and will their be any hp gain with the 24lb oppose to 19lb? Are 24lb for highly modded engines?
Thx.

Re: Fuel injectors.
You won't need 24lb until swapping heads/cam/intake. Even then it's overkill some of the time.
I'm assuming you're talking about the '88 in your sig. I'd do a 255 anyway for future use. Cheaper than a Ford pump too... If you ever do a dyno tune, install an adjustable fuel pressure regulator and at least a 190 LPH fuel pump before doing so. That way you can crank your pressure a bit if needs be... Aeromotive/Paxton/BBK FPR's are all made the same, hit and miss on if it's good or bad. My Aeromotive has been good for the last 20000 miles, but some have had bad experiences. Kirban is always a good bet. As for pumps, no matter what brand you get it is made by Walbro so get the best deal.
