And yeah 626gn in #5 symptoms greatly improved as I could actually drive it without feeling like something is drastically wrong until 1/2 to 3/4 load when it breaks up. Maybe my accell coil pack is a dud and my stock one breaks up under load. I could try putting stock module back on with stock coilpack and use the caspers thing to test if I'm reading you right it does work on stock parts just not with standard module or accell cp but if i throw both factory stock units on should give accurate reading. If the coil pack passes with stock module that would mean my standard module was at fault but if it fails then it could mean it's bad or mean both standard and stock coil pack are bad at least I could possibly narrow it down if it does pass to the standard module. Thanks again
