What injector size?

Hey guys, quick question. I have a 1996 saleen SOHC 2V with PI heads and cams, 3.55 gears, kooks long tubes, and a 75mm TB.
My question is that i have the stock 19 lbs injectors and need some advice on which ones to upgrade to. Im thinking 24lbs based on some other threads i read about this. Does this sound right?

The 19lbs max out pretty fast when you reach full bolt-ons, that's why Ford went with the 21s in 01. I would go 21 and maybe 24

24 lb/h, however you do not need a "calibrated" MAF if you get the tune changed so it knows about the higher capacity injectors. Callibrated MAFs are a kludge left over from the early days of EFI when tunes could not be easily (or at all) changed. They mess up the PCM's load calculations and are never needed on any engine that can be properly tuned.

Read more about "calibrated MAFs and why they suck" here...

I have read that the 19lb/hr injectors were at 90% duty cycle basically stock. Shouldn't injectors and a tune be near the top of the list for a performance GT?

If you can lock the door and walk away without turning back to look, you bought the wrong car.
