Fueling & Injection - Variances From offshelf 60LB Injectors

I am wondering if anyone can tell me if u have run across Variances from the injectors,I have a Tuner telling me that there are Variances ,that come when tuning these injectors,Basically i am trying to get my SC car Tuned & the kit came with 60lb injectors,He is telling me there maybe some Driving Quirks,There are Many people i know over in the Corvette Forum Running 60lb injctors with there sc set ups & Have no Quirks with there car whatsoever & They are making 500 to 600 rwhp on a4 & mn6 speed cars with stock Bottom ends ,Anyhelp Is appreciated/// ,This is what the Tuner tells me //// First of all, they have a 6% variance +/- from the factory. Yes, some flow around 64# and others flow around 56#. And, that could be from cylinder to cylinder. The only 60s that I trust to never have any quirks are the flow matched set. Do you have a flow matched set? Did you even know that about those injectors? It's one of the worst variance of any aftermarket injector. You may know me as a friend, but I'm also a professional tuner, therefore I'm going to inform my customers about the setup. Now i am Sceptical on what to believe :confused:

I have tuned lots and lots of cars on 60s and never had any issue with them after spending a little time to get the first set right. If there is some crazy variation I guess it's possible... is it an issue? No.

Thanks Bro,i Just Spent Bookoos of money Getting the car the way i want it & The tuner i talked to was having issues tuing Ford Motors with the 60lb injectors , I own a 00 c5 not a ford ,Maybe i should look elsewhere in having someone else tune my car,i dont wanna put the 402 in so soon :D http://i142.photobucket.com/albums/r87/vette3/HPIM0089a-1.jpg

I can test them for you in our injector flowbench for $80 if you like ? They will come back to you individually labelled so you know which one flows what .
I see them generally between 60-65 lbs. per hour but you never know
