Well I have an 04 GT and I am pretty sure I have 21# injectors and they are pink. Appearently I am running rich at WOT because the cars computer thinks I have 19# injectors when in reality I have 21# or something. The Sniper SF is useless.....upgrade to the Commando, thats what I am gonna do. That way I can adjust my fuel injector slope values or something....thats what Cliffyk said

hmm i'm wondering....if I set mine to 24# too maybe the computer will inject less gas thinking I have 24# injectors when in reality I have 21# so my AFR will be more optimal

Let me know how the injectors work out Evan.

I have said this before and I will say it again, it is NOT recommended that you make any changes to the fuel modifiers (including injector size) unless you have a wideband O2 sensor--or know exactly what you are doing and know for sure what pinging sounds like...

For new-edge GTs that came with the pink (21lb/h) injectors the base Special Forces tune will make modest adjustments to the Stabiized Open Loop Fuel table to lean it out a bit at higher throttle openings (it also richens it a bit at other points).

Here's the table comparing the stock tune for my '03 GT, and an 87 octane base tune created by Special Forces:



The numbers in black are the stock tune values, those in blue are the SF 87 octane base tune values. The highlighted area shows the leaned out values...

ok well it ran just fine with set to 24#

so i would have been fine leaving it on the stock settings?

and i finally got rid of the misfire so that is a plus

I would be listening very closely for pinging at WOT, at high loads and low rpm's, and at high rpm's, WOT, and moderate to high loads...
