Whippled and dyno tuned by pbdyno 2017

I put in the numbers from the dyno. I don't know where the default numbers come from. And the -D4 and 3.73 so obviously we'll get different numbers given different transmissions.That link you provided has the wrong torque curve. I inputted the torque numbers from the dyno sheet on page 1. I also used the 6R80 gear ratios.
According to your link I should shift at 8ksince when? that's weak-ass torque range. at 6000 the HP goes flat. This calculator says 7k but anywhere between 6500 and 7000 is good. I'm assuming MT82-D4 and 3.73 gears

As long as the next gear selected drops your RPMs to >4300 you're good.
28.4" wheels? I think I used 27. but either way ~7 grand +/- is good enough IMOOr i filled it out wrong??
on a 2018? I personally say no. Though if you disable the rev-limiter so you can spin to 8K or more, then yes there probably is some merit to it.So is the GT350 intake manifold a good swap or not?
According to what I can find, 305/35-20 is suppose to be 28.4” diamete. I haven’t gone out and measured them. Just went off tirerack just now on some pilot 4s and discount on the G2’s both give the same diameter28.4" wheels? I think I used 27. but either way ~7 grand +/- is good enough IMO
Yes sir you shift at a high enough RPM where your still making more than peak engine torque at the flywheel. So if your engine makes 420 ft-pounds and you shift say at 7500 when the engine is making 290 ft-lbs, take the gear ratio say 1.5:1 multiply by 290ft-lbs. So that would be 1.5*290 = 435ft-lbs so you are still accelerating until it drops below peak. Math never lies haha.So the basic idea is launch at the maximum torque point and shift at peak HP range where the drop doesn’t go lower than the peak?
Best manny out there. swap away.So is the GT350 intake manifold a good swap or not?
And if you want to get even deeper, you calculate and average out the hp in your range.So the basic idea is launch at the maximum torque point and shift at peak HP range where the drop doesn’t go lower than the peak?
What about on my old 2016?on a 2018? I personally say no. Though if you disable the rev-limiter so you can spin to 8K or more, then yes there probably is some merit to it.
