Well, I can see how you woulda been expecting more, but I dont know if I would have expected to see 160 at the tires. Thats ALOT of power improvement, and just because one dyno chart showed an exhaust made 10hp, another showed the head making 10hp, another showed the cams making 10hp, etc, doesnt mean you can just add up all 3 and get 30hp.
You going to stay with the factory injection? CIS isnt great, but its not all that bad, but the CIS-E is rather.....finicky...
