That looks like a 3rd gear pull with no shifts, do not know the rpm's, but if you mathematically figured it out, its probably roughly the same rpm. Just throwing this out as a remote possibility, but years ago, after I first started modifying, my headers would piss my knock sensor off due to the harmonics of them..... it wouldn't go into limp home mode or anything that serious, but on my year, it pulls out a certain amount of timing, if the perceived knock is still their, it pulls even more out....naturally, it pulls out way more than it needs too..... and killed power as long as it thought it had the problem. I do not know much about LT-1's or what you have done in regards to this already, so have no idea if that could possibly be the problem, but its something to think about. Hope you figure it out ! |
