00 injectors into 99 - retune ?
If I swap to the factory '00 28 lb injectors instead of the factory '99 26'ers, will I need to retune ?
How much will the tune compensate towards the larger injectors (STRIMS/LTRIMS ?)
I'm guessing a bigger change (say to 30 lb'ers + ) would definately require a tuning change...
Thanks,

Oops, maybe I got the years mixed up.
I'm looking at the 28lb injectors and fuel rail from Texas Speed for $60 to upgrade from my stock 99 26 lb'ers.
Would I need to retune if I use 28lb injectors, or is it plug and play ?
Will STRIM/LTRIM compensate for the change in injector size, and if so, how much (+/-15% of duty cycle, right ?)... 26 to 28 isn't a big jump... I'd think a tune would be required at some point though...

I made the swap a few months back with my ls6 intake and never retuned the car. Although it would have been best to tune it, I haven't had any problems. The car still runs hard, and there was no noticable effect on gas mileage. I figure I'll get it all tuned when I decide on a cam.
