Uncategorized Ejk tuner help April 22, 2016 dstech Installed my EJK 3.5 this evening and went for a spin. It idles a bit rough and it’s poping and missing pretty bad especially between 2500 and 3500 rpm’s. The settings on the tuner are for stage 1 exhaust/ intake mods. Any thoughts are appreciated.
