Thanks, I think i found my issue. OEM o2 sensor was not readin correct. had a spare and replaced it now it is reading fine, altered closed loop max rpm to 6k and got it to go higher than 3000rpm without spluttering. Have just created new VE table and timing maps plus a few other bits in between will put new tune in in the morning and see how it goes. Fingers crossed i think im on the right track

Hi Revlation, I sorry to say that I don't do any tuning outside my own kits these days. Suggest you post it as a specific question on the forum and I'll probably answer if it's something simple. Cheers Brett
