Its running about 20-22psi it goes off the centre pod anyway since MSD set it up and put a new one of their chips in a month ago. The car boosted fine after that and many times too it was 14 degrees when it missed as i checked the temp out of curiosity as i left my house. When set up it was 20 odd easily during our summer so far

Anyway spoke to Kenny today who has suggested going to the AGPP12R plugs and possibly changing the coil packs. Will start with the cheaper of the 2 and see how it goes for a while. Weird though as the PP8 that are in are fine.

By the way............whats a heat wave,cant remember one in the last 4 weeks
