IDX +70 Injectors
Hello All
Does anyone have any experience with these injectors? I'm curious as to how well these work idle and low loads, and if there were any problems at low speeds. I have to do my power increases in steps, and if the +70's are tunable so I can get them to start with instead of working up to them from +30 or +50. Thanks

Work ok if you plan on running high percentages of Ethanol(E70+). On pump gas they are rough to tune because the pulse widths are very low at idle/part throttle. But most needing this much injector normally are not running pump gas.

Thanks for the info. Current plan is to run E85 exclusively from the pump, which is probably more like E75-80
