SeanR32GtSt Posted August 1, 2018 Share Posted August 1, 2018 So occasionally when going through the gears at almost full throttle I will notice a little flat spot in the rev range that comes and goes. I’ve replaced the coil pack loom and spark plugs. Last should be the packs themselves. What’s a good option? Splitfire or yellow jackets or something else?

GTSBoy Posted August 1, 2018 Share Posted August 1, 2018 Also consider fuel pump might be going soft, AFM might be unhappy in some way (dirty, whatever), injector(s) might be a little sticky. All of these things can be a bit intermittent too, like coils. 1 Link to comment https://www.sau.com.au/forums/topic/474626-rb20det-noticing-some-flat-spots-in-rev-range/#findComment-7882424 Share on other sites More sharing options...

All of these things can be a bit intermittent too, like coils. I also have changed the fuel filter recently as well. I’ll start with coils next and if not that then I’ll look at a slight fuel pump upgrade.
