I just purchased a 2016 Overland with 58000 miles and it's bone stock. Like many have shared it runs out of breath after 3k rpm and I have a slight oil leak that appears out of the EGR (I need to disassemble and verify the source. I would like a tune but not yet ready to perform a DPF deletion. Anyone have recommendations on which tuning solution to use? I am leaning towards Banks but open to suggestions. Any other moderate changes I could/should make? Thanks! And sorry I'm a bit vague, new to this forum and new to my diesel JGC.

Firstly, I do not have experience with Banks, so cannot comment. I have experience with Stage 1 (emissions intact) engine tunes and trans tunes from GDE, SFT and MRTuning. I think GDE was overall the best... but not currently available. Both SFT and MRTuning offer tunes via handheld flash devices, which is awesome. Easy to tune and de-tune on your own for dealership trips. I personally like the tune from MRTuning better than SFT for my driving (mixed city/highway driving and little to no towing). That said, both are much better over stock.

Do you have more info on the MRTuning? Is it just a ecu flash or what exactly? Also what gains did you get hp torq mpg

In your opinion is getting a trans tune along with engine tune a must? I recognize that the tranny in stock tune is very soft in its shifting. The dead pedal at stop signs drives me nuts, I out it into sport mode as soon as I hit a road with many stop signs as I find it corrects the dead pedal a little bit. Does the engine tune fix the dead pedal? Or would I need a trans tune as well to fix this?

I guess I'm inclined to say yes. My first experience with tuning was the GDE Hot Tune. I thought it was great, but still had some minor complaints about turbo lag, so decided for the trans tune, which further improved response. Unfortunately, I have not been able to restore my GDE trans tune since getting the AEM and looked to other vendors.

Since I had good experience with the ecu/tcm trans combo from GDE, I have opted to do both with other vendors (SFT and MRTuning) and can't really speak to their ECU tunes alone.

Both tunes are much better than stock. I felt that the SFT tunes resulted in a more aggressive driving experience (holding gears longer and generally louder because of this). The MRTuning tunes resulted in a more "normal" driving experience, in my opinion. Thus at the moment, I am using the MRTuning tunes because of my driving preference. The MRTuning trans tune has been the smoothest shifting tune I have tried.

So, I guess I haven't entirely answered your dead-pedal question.. because I can't. With the exception of GDE, I've installed the tunes simultaneously. But, there's no reason you couldn't get the ECU tune and try it and then decide for yourself if you want to try the trans tune.

I will say though that with every single tune I have tried, I still get a random time (like once in every 20 starts) where I push the accelerator and find myself waiting for the power to show up. I'm not sure what causes this phenomenon.
