So I found some time to tow with this truck. The trailer was roughly 4K lbs & I was on the stock tune. It has plenty of torque at part throttle in the low rpm range but if you wanted to get up to highway speed fast it would need to be tuned. I wrote a tow tune for it that is very mild but really helped it get up to cruising speeds effortlessly. Made another revision that helped it out a bit more. I then had my wife drive it while I data logged it & got her opinion on it. Her daily is a Pontiac G8 Gt so she's used to throttle response & high rpm hp, both areas where these trucks are lacking stock. She asked why does it wait so long before it goes? Well the answer is low boost fueling & emissions crap don't work well together. I worked on that a bit & had a tune that worked well enough without creating any soot accumulation codes with some city & highway driving. I wanted a little more response & added a bit more fuel down low. That felt great but after a morning of running around town enjoying that it kindly asked me to continue driving while it cleaned the exhaust. I did that but soon got a reduced engine power message.
Looks like it's time to move on to the fun stuff

Went back to a stock delete tune just to see what that was like. It throws a small puff & hazes a bit stock so I'm not surprised it gave me trouble when I added power down low. I installed an Edge Insight with EGT probe & drive & boost pressure sensors. Now to see how it responds to more fuel & boost.

I didn't make a video but I will post one soon. I spent a little more time getting it to be happy with the deletes & gutted stock exhaust. Now it runs great! It's like a whole new truck... again

Got a tune dialed in that I really like for daily driving. Quick throttle response & smooth progressive power. No lights on the dash. It's completely happy in it's current state. I increased transmission line pressure a bit and now the shifts are very quick. A had a lot of running around to do yesterday so I fueled up & reset the trip odometer to check mpg. At 211 miles I topped it off with 8.0 gallons. 26.3 mpg hand calculated.

I assume you had to do some work outside of EFILive to get the deletes working properly?

Or did you start with a deleted base file from someone else?

Before anybody asks, it can do the same burnout without the smoke, but why would we if we have full control of the ecm

I know I hate these tires! This will be the last stock turbo burnout this little guy gets to do. My twin kit ships next week. I'll post another video then that might be more to your liking
