Makes no sense to me, both of those tires sizes keep you in 5th gear before the traps so a larger tire should never be faster here. Especially when it's also a change to a heavier larger wheel to boot.

The larger tire also has a larger contact patch, so increased grip could be a factor, especially if it was spinning on some of the gearshifts leading to torque management as mentioned.

Have to spin the tires at least a little to get a good 60 foot as launching softer will bog the engine. Although both are 1.79 I could have been going faster through the 60 foot gates because of more traction with the wider tires. (Bog off the line a little, then get into boost hard with grip) and (spin more off the line while in boost but have less ultimate grip) can result in the same 60 foot times at different speeds at the end of the 60 foot. I bet this is the culprit.

3 things get the gen2 making way more power than the gen1
1.) all 15-17 trucks have same size turbos, but the gen2 3.5 has dual injection so they've redesigned the cylinder heads correspondingly as they no longer need an odd reversion lip to clean the back of the intake valves and thus the headflow is superior
2.) the exhaust manifold is LIGHTYEARS better on the gen2 3.5
3.) harping on dual injection again, it gives you the fuel capacity you need to run the power it's actually capable of making. I'm making that power you see up there at 80-82 lambda, which is about as lean as i'd like to go with the smaller amount of Direct Injection blend i'm running
