currently mapped to perfection by jamie but going to try a new design tubular manifold and few other bits for the cvh so don't want to drive 3hrs for him to strap on rollers then after a few mins say it's not doing what we hoped then i drive 3hrs home to make a new one with things that were wrong to then re book and repeat whole process over again, even someone that rents out a rollers close would be good as then try a few different back to back tests out and rule a lot of factors out
