For you 5.3L guys w/ the stock 191/190 camshaft. What have you guys found to be the ideal shift point settings?

I think peak, even though it is relatively flat, is around 5500rpm. With a 300 rpm extension, I'm thinking a 5800 1-2 shift might possibly be ideal.

Now, what about the 2-3 shift? Right at peak hp?

I managed a 5.9 0 - 60 w/ a 2.3 60' with a 6,000rpm 1-2 shift. - exhaust & cai ----> G-Tech meter

If I stall it to 1500rpm & w.o.t. after that, I get no traction. I've found best to do a medium pace stomp from idle. How do you guys come off the line on street tires?

penny for your thoughts... on this or related.

I agree, I set the limiter at 6200, 1-2 @ +3 ( would shift at 6k) 2-3 @ + 9 (shifted at 6k) that was with 3.73's and 30 in tires (255/70 16's).
