Quick update: the new Whipple tune shifts at 6400 in normal and 6400 in sport after 3rd gear.
Also the knock sensors add 1 degree of timing every cycle (used to be .5 degrees) which brings timing in much faster with good fuel.
Seams like whipples tuner reworked the knock sensor strategy (a lot) and that’s were the gas mileage increase came from.
Transmission shifting is much improved but I spoke too soon about the bad 1-2 shift at very light throttle being fixed.
It’s not fixed.
It’s like the trans mission doesn’t know which gear to go into, 2nd or 3rd, it hangs and rpms flare up then shifts to 2nd hard.
Even if whipple was shifting to 6600-6800 at wot, I would be moving to a custom tune based on that bad 1-2 shift alone. I drive a lot at 0-15 mph at very light throttle (which seems to be the only time this bad shift happens).
When you guys are reading IAT are you reading IAT or IAT2? Granted I have a Roush but my intake temp is 20-25 over ambient and IAT2 is 15-25 over IAT. So I could be 35-50 degrees over ambient. I’m running a triple pass give AFCO HE with dual fans.

The ngauge I use has pids for iat and iat2.
I’m reading iat, iat2 shows -40 all the time (which means it’s not used in the strategy I have)
The 2015+ use a MAP sensor (no MAF) and the MAP sensor has a Temperature probe built into it. The MAP sensor is after the intercooler (in the intake manifold) whether it is a Procharger or Whipple. So the regular IAT is the intake charge temp. I know the Lightnings used to have 2 IATs from the factory. The first one was by the MAF which is by the Air Intake (air filter). The second one is in the Intake manifold after the Intercooler.
its shaped to seal off at the hood but when I installed mine at the highest position it left bout a 1 1/2 inch gap .
The Whipple air box is poorly designed. I haven’t even put the included gasket on the top of the air box because I don’t like how it is designed. I need to find or engineer a solution.

Let me know when you do...
I was thinking about trying to find a s&b or something like that and make it work.
