Rb25 splutter !

Morning little intro to the build r32 rb25 with a gtx3582 haltech platinum pro, 1000cc injectors 460 walbro fuel pump “maybe larger” with new lines and relay setup, new fuel lines an a FPR 1200. Made 350kw and Have had the car back now for a couple weeks haven’t had any real issue but this Sunday I got my first issue…. I generally fill up E85 at astron yagoona and with a quarter tank and on the way to a cars and coffee I stopped off at minto and put a full tank in it. after about 10 mins of driving and letting it all settle in the car started to misfire and splutter? nothing consistent but noticeable? on the way back spent about an hour on the free way at 110km/h cruising at about 3000rpm and this is where the car started to splutter intermittently and wouldn’t give me any boost if I dropped to 3rd gear would stop and let me have boost then start again when I would consistently cruise at 3000rpm this is where progressively the splutter would get more consistent. im about to check the fuel but the e85 at minto has always been consistent, I have aftermarket r35 coils and have pulled them apart and they look good to go and injectors sound to be doing there job? At idle I don’t have any issues when i let it idle for a while and gave it a few solid revs and nothing? When I got off the motor way and was driving city speeds/ traffic “50km/h” no splutter? Could it be a: fuel issue? coil issue? tune issue? will go for another drive to see if it starts up again and see. any helps appreciated!!!!
