I'm looking for some advice on where to have my tuner set my shift points. My mods are in my sig... I've ran my best times manually shifting the truck at about 6000rpm, which is probably 100rpm shy of the rev limiter. The engine has about 100k miles(maybe a lot more, lol) and stock rod bolts, so I understand keeping the rpm down a little low. Right now the 1-2 shift is ~5800 rpm and the 2-3 is ~5600rpm.

Here's some dyno threads with similar engine setups:

What you guys think?

 

Well thanks everyone, you guys were very helpful, lol. Think I'm gonna try 6300 on the 1-2 and 6200 on the 2-3...

 

If it were me i'd say 6400 to 6500... That cam shouldn't have any problems making power at least till 6500...

 

IDK why you would even shift it that early anyway... I used to have a 99 model LQ4 with a 221 cam, STOCK bottom end including rod bolts and it seen 7k many many times...

 

I guess Nelson forgot to change the shift points when he did the tune for my truck, idk. I'll tell him 6400 for the 1-2 and 6300 for the 2-3 and see how that works out.

 

i have mine set at 6200 1-2 6200 2-3 on regular then on tow haul i have it bumped up another 100 with a 6500 rev limiter its perfect for me

 

mines set at 6200 on regular and 6300 on tow and haul... i might bumb it up a bit since i was told i can get power till 6400-6500 on this cam.. it might be small but its got potential..lol
