Well this doesn't seem very promising. Anybody know about the L5P turbine housing?

So when is GM going to give up the private keys for the SHA256? Does Ben know how the infrastructure works on the new ECMs at all?

I'd like a tuned and deleted L5P not a fooled one running like crap lol.

I wouldn't think it'll happen for years. But the AFE module just bumps fuel pressure and boost. Doesn't make it run like crap. No it doesn't add 200hp but it makes the truck fun to drive. It does make the engine a little louder but nothing that bothers me.

How much more fun n to drive? Have you tested any mph gains in a measured distance?

Going to the track soon. Truck only has 1300 miles. Hopefully Saturday if it doesn't rain. 4wd launches are cute. Stops pulling in 5th. Feels like low 14's. Beats scion tc's with ease

Stock sucks, I can't leave anything alone . But for keeping the warranty I think it's a good option.

What have you noticed on fuel mileage and regeneration with the module?

It's only been in for 300 miles and the truck only has 1300. When I get more data I'll post it up.

Finally installed the AFE intake. I'm really surprised how much better the truck feels. Throttle response is much better. I really hated how you'd slow down for a red light and it turned green before you stopped there would be a delay before the truck would come back on. That's almost gone now. Doesn't feel faster but it sure is fun to drive now. Truck doesn't fall on its face in between shifts either.

Where the stock box connects to the fender is almost blocked off. It almost seemed like they're trying to get the ram air to work more.

I did notice with the intake the truck is a lot louder (could be why gm didn't open up the fender connection) would be curious to cut out the restriction and try the factory intake.

Couple things I noticed. When in 4wd I feel like there's torque limiting happening 1st-3rd gear, 2wd actually feels faster even without being able to launch. Traction control does a decent job but if you turn it off before the 1-2 shift the truck is faster the rest of the run. If you press the brake pedal too much it will not let you power brake the truck in 2wd, lightly press the pedal just enough to hold the truck back. If using 2wd leaving around 1400rpm works pretty well.
