I have a set of 42 lb./hr. injectors for sale in the parts FS section. Those would work well for you! Also the injectors you have should be 26.6 lb/hr. injectors. I would definitely upgrade injectors with any boosted vehicle. Just make sure you have it tuned properly to utilize the extra injector. Otherwise you won't be able to get the car to run properly if you change them without tuning.

I thought the Denali's had "spider injectors."?????? He would have to change the rails and the wiring to make those injectors work......I could be wrong but I thought that was the case.......

i was going to ask you that because from what i found out today it does have that spider design i dont think you can even change them i cant even see the injector from the top of the engine there inside the upper intake

I mean with modifications you can get anything to work....just dont know how much you want to spend on it......I think you're biggest problem is the tune and the fuel pump.......with 6lbs of boost you would be maxing the injectors out......but the stock fuel pump might not put enough to feed the motor......I wouldn't be gunning that thing until you get a tune on it.....talk about getting expensive.....you'll be buying a new motor....
