That would do it...I was just starting to think about that last night. Are they the same impedance as well?? I know on som cars it is important to make sure you have your injectors in at the proper angle ect.These are new injectors right? If not do a flow test if you can get the proper tools.

yes well i knew that if i changed my injectors i would need a tune so i did it just to see how the car reacts to the bigger injectors and its crazy............the car stalls, need to rev 1,000rpm to idle w/o stalling.....extremly rich...(smell the extra gas outside of the car...like 8mpg...lol...and totally not worth it with out a tune..............oh by the way the stock ones should be 19lb, thats what the 99-04 gts got on them....

Without a custom tune its still going to run like ****, and you should still not be using cobra injectors as the spray pattern is completely different.

Almost zero chance you can just pi swap and then toss in some 24s and a MAF and call it a day without a retune.
