I'm not tracking the truck... I do love that I'm explaining how truck forums require lowered expectations and the reply is someone who didn't bother to read carefully, though 😂

I wouldn't be too hard on them - they just pitch what they've been told and often don't understand the different nuances between models. A Chevy dealer once tried to convince my buddy that he was *way* overdue for an oil change and serpentine belt for his... electric... Bolt. As far as forums...

Hope they sold you blinker fluid, too...

Was 15 MPG the actual mpg indicated? Or are you just assuming a mileage? The range estimate adjusts to the current mpg, so if you were actually getting 10-11 MPG at the time the estimate would make sense

Guessing you already know, but use worm gear clamps (not metal zip ties) and wear gloves to save yourself a lot of trouble

100% this

Shorties "generally" don't require a tune because they generally don't improve VE enough to matter. These engines run off of a VE table, so yeah you should get a tune if you plan on modifying it.

Totally agreed that butt dynos don't disprove butt dynos. That being said, after watching dozens if not hundreds of cars get on and off a dyno, I can say there are *very* few cars that benefit from an intake and exhaust nowadays (beyond ditching weight from the exhaust) because modern ECU's...

Just a reminder to everyone that the proper gear lube is dependent on your differential. 3.21/3.55 diffs use 75W-90, while 3.92 differentials use 75W-140. Both require additive/ friction modifier if you have the limited slip.

Go to an auto parts store and get the engine code read/ reset.

Out of curiosity, where is the BCM located?

In closed loop only. If your coolant temp isn't high enough or you're at WOT, the O2 sensors usually aren't doing squat for you. I'm not sure if these new engines are running widebands yet, but if they're still narrowband you really don't want to use that for fueling. Hemi's can either use a...

It's worth pointing out that will *still* need a tune and it'll never pass an emissions test.

These are shorties... just keep in mind that if your headers don't need a tune, it just means they don't add power. If getting a tune sounds expensive and complicated, you're really better off just leaving it stock. Catback usually means it starts at the cats and goes back. It does not come...

Kooks is one of the few header companies that actually engineer their stuff - some of the best. This is the biggest catch. If you add *good* headers, you're changing the volumetric efficiency (VE) of the engine. Because we have Speed Density engine management, VE tables and a manifold pressure...
