can get a set for free....sort of....any value to them over the stock 21s?

They may hold another 50 hp or so, but they won't give you any added power with your current setup. Plus you'll need a retune to make them work properly. If they're free then grab them. If you have no use for them, then sell them to someone that does.

lol I got mine for free to when the shop built my motor thats the only reason i have them and the udps and the cai. He just gave it all to me cause he took longer than he estimated. I dont think your really gonna see much of a difference if any at all to be honest

They won't make any difference.

Having an AFR leaner than you care for it to be at WOT is the only reason to increase injector size--otherwise the installed units are doing their job...

ok i just thought that you could pick up a little power by switching to the larger injectors
