My fuel pressure is good, about 43 then bumps up when the engine is running. Also holds pressure for a good while, I don't seem to have any leaky injectors, not to say any are not clogged.
I'll try and check the CTS here in the next day or so, I did a bench test with an ohm meter the other day and it seemed ok, im betting it spikes radically when it warms up... but it seems to act up like this cold and warm.
I'm a little unfamiliar with the the octane settings on the LT1, thats something thats programmed and can't be adjusted manually, right? and I'm not sure how octane levels affect the driving characteristics. I know that running low octane in a high comp engine will cause pinging, but this is MUCH worse than a ping. It almost feels like there is either way too much fuel getting dumped in or not enough. when I try and power through it the popping the stop, but as the car pulls you can feel the hesitation, like 2 or 3 cylinders are not hitting. This is as best as i can describe it so far, i got a video of driving the car but you cant really hear the popping too much. I'll post it if you guys think it will help, it was mainly just to get an idea of what RPM it starts acting up.
