It is not the problem of the injector that would cause your motor to blow up. The slight variance in injectors is not going to cause any problems with your tune.

If you believe that I have some swampland to sell you in Florida.
Coming from a vendor that is not a very encouraging...

With a possible 7%+ variance in injector flow rates from the factory one could quite easily take out a cylinder or have chronic detonation problems in a number of cylinders. These variations can also cause idle and tip-in problems.

I am Sure the RaceTronix Injectors Are Great. This Thread should not have stepped on RaceTronix Feet if we are going to talk about the 60lbs injectors we should start a new thread.

FYI i sold 6acres of "swapland" 2-4ft underwater . I'll Buy that land you want to sell.

Nobody has stepped on our feet. Mototron and Siemens injectors aside, the issue is about telling customers that mismatched injector flow rates will have no ill effects on a motor. The fact that they can need no more proving than the fact that the moon is not made from cheese.

No we do not have any cheese or swampland for sale.

Thats silly. If we had some kinda sequential LS1 edit, would you let me pull 7% of fuel on your back two cylinders only?

I think not

Whatever it takes to balance the fuel delivery for even EGT & A/F per cylinder.
FYI some factory PCM's have individual correction as well as DFI Gen 7's and FAST PCM's for this very purpose.

Silly, definitely not!

Im talking about Nastys response, that off balance injectors could in no way be harmful. They could defintely do something - team up the weakest injector with the rear cylinders in an LS1 and see what happens

I know there are variances cylinder to cylinder, I work on LT1/LS1 cars for a living, and definitely have seen a trend from dead cars brought to the shop, 7 and 8 always pop

LT1s have a cylinder balance function in the factory PCMs as well
