2015 lag vs 2014

[golfer]

in the short time I've had my '15, I think the 'turbo lag' may be more in the function of the transmission shift strategy.

It definitely runs up through the gears quick...simply tuning a different trans shift strategy would almost certainly add 'boost' without touching the fueling tables.

(mines bone stock still)

After having my Fummins with good size compounds on it I think my 15 spools super fast. lol

If the tuning is good it should make 10 psi at about 1400 rpm or so, or at least my 64mm street max does. yes there is more lag right off the bottom but man they pull so much better throughout the power band.

Im pretty happy I didn't buy a 2015 and stuck with the 2012 with an upgrade, tuning seems to be a non issue on the older trucks.

That sounds good, assuming BP is in check.

Yep, I could make 12-15 psi by 1500 with the 64mm on my 2015.

The stock turbo that is on it now will making positive boost around 11-1200

That sounds good, assuming BP is in check.

At 10psi his drive pressure is probably less than 15psi. Ebp is only an issue with a larger than 11-14 pump and only at approaching 4000 rpms. And at that it is only a mere 1.5:1 ratio or so.

A little off subject but I don't want to make a new thread just for this. I just put in the IDP race tune and it's just not a DD I think. It's laggy in the low RPM and smokey to. Can anyone verify that the hot street tune is better for a DD?

Also I'm in a 11 with a street max so maybe no one has even tryed this yet..

I still stuck at 10psi at around 2000 RPM...

 

[jcain]

is that 10psi in 1st gear or any gear?

 

[Cheap6.7]

1st at take off. I don't know how else to go by there's to much variation in what's going on in the truck. So I just base it off of normal 20% throttle at dead stop to 10psi. I know that it can be better just want to know if the other tunes run diffrent like hot street or even a row tune. I am also working with PIP on there tunes and I do need to say they have been absolutely great to work with.

No I just talking about my day to day, as I get into town there are red lights and A lot of 40-55mph with a lot of passing and such. In a nut shell I'm just seeing what's normal for all of you guys.

Idk why you guys have so much lag. I need to take some videos of my 2015. I can punch it from a dead stop and blow the tires off with no brakes.

Is that just with the tow tunes? The other guys with the Innovative tunes are praising them and saying that there is less lag. I'm sure it's that every single person has a different opinion on what lag is to them. Have you tried the hot street tune?

 

[theplumber]

No all the tune are like that. The tow tune imo have less lag but it's not like my 14

Did you mention that you have a different turbo setup? I'm Sure you did, but it can't hurt to ask. I'm Running the race now on my '15 and it's been great. The only thing I'm not used to is that with this transmission it shifts so many times so fast that it doesn't feel like it's strong, but as I look around and at my speedometer I know it is lol. I think they have a different feel than the previous combinations because they shift so much. My old 6.0 felt great as did my old 5.9, but that's be they both held first longer.

Yes they know of the modded 15 charger. I feel the same about the fast shifting.

This definitely is one of those times when I feel someone should yell..

Swap a 4r100 in it!

 

[sootie]
