G'day, the curves are right for that cam, torque about where you would expect it, your exhaust is knocking about 10 HP off it, better intake will help if your current one is a bottleneck, bigger injectors will help if your current ones are at or close to max duty cycle, I don't know what you know about road tuning so I can't say if you can or not but it is possible with power vision, I've not used it myself but many do, what did your last dyno tuner say about your current set up?
It was done by Tim at twin tune in minto.
It rides really well very smooth delivery but you do notice the lower end lugging if I'm being lazy and not down shifting.
5.5 injectors, SE 55mm intake manifold, Woods 22XE cam kit, woods push rods & lifters, Supertrapp exhaust along with SE 1275 clutch springs, Evolution Compensator and a trask trans cover (which helps ventilate the crank/engine) this are my engine mods, most of my parts were though Fuelmoto USA
Have you noticed any difference with the teask ventilator?
