Default Dirty Injectors

Well I had thoughts of getting rid of my 1995 Camaro Z28 A4 but I think I'm just going to keep it. I got it dynoed last November and the injectors were dirty and the knock retard was killing power from 4000rpm up. The car shifts at 6000 rpms so I figure I'm losing some what of 2000 rpms of power. If I was to get a set of stock injectors to correct the problem and go get a better tune, how much do you think this would help me out performance wise. I run 13.80s consistent with the dirty injectors and street tires. Also what are the biggest injectors that I could use on a stock 95 Z28. I just put a new stock fuel pump in it and don't wanna have to change that out again!

How many miles are on them..I have a set of Injectors here, they came off my LT1, and they haven't sold. I believe they were one of the things that the porevious owner replaced before I bought the Car, they have about 40K on them. They ran great for me, no problems at all.

Well if you're staying stock, then don't go any bigger than stock. However, you could benefit from a simple mail order tune.
