Yeah , interesting. The stock GT fueling is different then the Bullet, I'm sure. But I see similarity's there when Cams are installed. At 100% throttle up there in the top end, I usually find that fuel is added.. but not much more. Cam profile and how your intake is flowing... and the how stock fueling is will play a roll. A Vacuum gauge hooked up to the intake manifold would tell you though, at wide open throttle and at red line. Down low at idle and start up, in the smaller throttle openings and RPM's... yeah , similar to the Bullet's. You likely don't need as much fuel down there now with the bigger Cams. That's effecting your idle a bit I think. There is likely LESS manifold vacuum now... particularly at lower RPM"s and at idle. So less air flow down low ... less fuel. For your idle, I think you might need to pull a some fuel out between 500 and 1500 rpm's. When they create a canned map, they generally don't tune that 0 throttle position at idle. And depending on what your shooting for as far as air fuel ratio on a Dyno or with an auto tuner ?.... I would venture a guess , that a little more fuel would be taken out and it would perform a little better with your higher compression ratio. Anyway, I think it will be interesting to see after you get it on that Dyno.
