[QUOTE="Tim @ P.I.S., post: 1314534, member: 744"] Unfortunately a lot still do. I have seen it first hand. All you need is a scanner to watch it. Here's your issue, can anyone buy a set of 300/200's and run in there stock truck and tow a house? Sure they can. But your tuner will hate you and you just spent nearly twice as much on a set of injectors that do the same exact thing you want to do. Any tuner will tell you, as several have told me it's easier to tune an injector that needs say 3 ms to completely empty verses one that needs 2ms. The shorter the people the more work is going to be required to get the best outcome. Most control fuel with pw. Once your injection window is so little it will be harder to control. Fortunately for years many injectors took for ever to fully empty. That made it easy to tune. I couldn't tell you how many sets of 250/100's we have sent to us to go through because people just are not happy with the outcome. Many many sets we run on the bench and have to run at 5ms to get all to empty 250cc. No lets throw another wrench into this equation. Two injector companies make the same size injector but have completely different flow rates at various Rpms. How do you think that's going to play into your tuners efforts? We designed our own version of injectors that some tuners saw first hand they had to make several adjustments too and couldn't figure out why. The flow bench gave them the answers they needed. In the past they were tuning for say a 250cc injector that they thought was actually giving them 250cc. Wrong, once they started getting 250cc they had to go back and adjust for it. That is just another thing that makes tuning not so easy. Fortunately you have companies that have worked with tuners for years to be able to package together options to do just what you want to do. So the consumer has options. Buy a set of injectors that WILL do what you want and get a tune that has been proven to work and do what you want 1,000 times or buy twice the injector (size and $$$) you need and spend possibly months with tuning revisions to get where you want to be because it is a combo of parts a tuner isn't familiar with, Your choice.
