I've uploaded the 2 Rolling Road print outs because I dont really understand them myself.

mine witha scorpian slip on was 112.8 but that had not had the jets or filters done at that point its back to bog standeard now 112 with just a slip on was good tho im told by mr dyno man

Hi

First graph is power against revs, 2nd is power against speed through the gears (although on stock gearing a true 155 or so is the 10k red line in top).

Looks like the fueling, at least from 6k, is pretty good. Below that it is a bit lean, but that is possibly the slides taking a bit of time to react properly when the throttle is whacked open hard at low revs (ie, slides are damped too little / too much). If so the make sure that any of the mods to the slides for the dynojet kit have been done (ie, different springs and / or smaller or larger holes in the slides).

All the best

Around 13.2:1 is best for power on a N/A engine Ben. See on the top graph, where the power flattens off at about 50hp, now look under it to the air-fuel mixture it goes lean right there to 15:1 or so. The dyno operator could have pointed that out to you TBH. Lift the needles a notch and you'll probably improve that flat spot. Might make it a little richer further up too but you have room to play there especially between 5 and 7k rpm.

By the way, the speed chart isn't much use and you have no torque trace - having one over-laid on the BHP graph gives you more useful info.
