Has anyone tried a tuner or boost controller on the 2.7L yet?

Mike Borowski · March 10, 2021

I am perfectly happy with the 2.7L but obviously tinkering is fun. Has anyone tried a tuner or universal boost controller yet?

I have a nephew that runs a tuning company. He want to put my truck on his dyno and see what he can do with it. But, I’m reluctant.

You should do it!

Maybe when the warranty is up! Even though he is service manager at the dealer where I get my work done. He says he wouldn’t deny my warranty work if he tunes it.

You must have some small balls or something. I chose the T4 over the 5.3 due to instant torque and overall responsiveness. Sad to be you.

Yes there is a dealer option for that! It’s the 5.3L V8. Much like the guys who wanted to mod their K2 4.3s for more power I don’t understand why you’d buy the smaller motor just to mod it trying to achieve what the optional motor offers from the factory ? When I bought my K2 the 5.3 was a $600 option with incentives, you’ll spend that on mods in no time on the base motors.

The people that want to mod their 2.7L is awesome to me. It is no different than anyone wanting to mod a 5.3L or 6.2L. To each their own.
Some of you who have commented or should I say “belittled” them for wanting too, need to look into the mirror. Who cares what size motor it is. Let them mod it. It’s their money, and the age of small motors and turbos is upon us, whether we like it or not.
As for the “It’s Tim” gentlemen, do you ever offer anything to this forum? All I’ve ever seen is weak sarcasm from you!

Even in stock form I like the 2.7 better than the 5.3. For my mostly city driving and family car, the 5.3 was an unresponsive dog. I have no problem admitting I don’t haul anything and needed a larger car for the kids. I like some fun acceleration that’s about it. The 5.3 got worse mileage and was not as instantly peppy around town.

Thanks. Not that I have to justify myself but I like the 2.7. I just wanted to tinker with it. When I got my truck during the heart of the pandemic there was slim pickings, I had to hunt down a 5.3 and a 2.7 and I chose the 2.7. I like it.

i just got my 2.7 and only have 50 miles on the truck. it is our 2nd car so it sits alot. I was also looking into a tuner for it, not because it lacks anything, but it is a hobby to add to the trucks i own and i was interested in seeing what other truck lovers have tried.

Look at the rpm increase to get the extra torque?

I want to know how the heck they can increase the TQ by 72 ft lbs on this little motor but the HP doesn't change at all? Can someone chime in that is more experience....
