I keep reading about these two different injectors. How much of a performance gain could one except? The setup would be on a 6.2L with banks siderwinder turbo and 19:1 pistons, stock injection pump, on a 88 blazer. I got a quote from Tim at Accurate Diesel for 240 for the 2100 psi vs 188 for the 1800 psi. Excluding the core exchange, also these will be short injectors, b/c the turbo kit calls for it. I mean 50 bucks difference I my always get the 2100 right, just so I have them. Thoughts, Woods Edit-Would there be any difference in fuel mileage between the 2?
