Ah 100% check is sensible! The meth mix I used was 50/50 so il take your reccomendation of 80/20 more meth to try and combat the timing. Inlet temps look good ! 32 degrees at full chat and outside today in sunny newcastle it's 24 degrees outside! Thanks for taking the time to talk to me today and for looking on here to help me, much appreciated. Again thanks for your help today Nick, of it wasn't for people such as you and Bill I would be lost. 100% it will have been living on the EGT zone. It was a blistering hot day on track and the stupid puny hybrid K04 I suspect just turned into a heat pump. Talking to Bill, and credit to his mapping, it's pulled timing, dumped fuel and this explains the "hic" I could feel. Accelerating through 3rd, 4 th and finally into 5th the EGT must have been astronomical. This also explains how on a lower boost map the "hic" in 5th didn't happen. So Next is new EIX plugs with a smaller gap, 80/20 meth, an order to Bill for more DS3000, and to book Cadwell Park and pray for cold weather !
