The truck is pretty sluggish off the line already, but causes more issues with the TC locked up on hills. I did notice that this became more of an issue after putting on the hydra. I had an older SCT plug in tuner for the last 10 years or so and never really noticed any issues on hills because it would just kick down pretty quickly and away I went. With the Hydra chip, it definitely wants to try and lug through instead of shift; can that be accounted for in tuning? Will I noticed an even bigger jump in the TC/off the line/lugging issue I had going from SCT to Hydra when I jump up all that power with the new sticks? I am hoping that I can get the new setup going and run some tunes that account for the tire size and gearing until I save up to have it regeared, as I agree a 4.30 gear would be optimal.

Also, I am running the canned tunes from PHP. I have to think that the shift points are thrown off due to truck not realizing actual speed. I know the VSS doesn't consider tire size, but I still think there is an issue there because going up hills it just does not want to down shift unless i hit the brake hard and then throttle hard to force a down shift.

See if PHP will modify your stock tunes for the tire size.

@MeTo I sense a little sarcasm! Haha I'm assuming you went through that process and were not impressed?

@[email protected] I will be getting all the upgrades put on here in the next few weeks so I am not even going to bother trying to change the stock tunes. It really isn't that bad, but I definitely notice it because I know it is not running like it could/should.

Makes a lot of sense regarding tire size/gear ratio with tall tires but what about the turbo outlet size, .84 or 1.0??
Corey can tell you more if youíve got the 1.0 as he had explained to me which the smaller size will spoil quicker/no lag.
I have a KC billet wheel in stock turbo currently .84 deleted outlet on PHP canned tunes, 3.73 ratio on 275/70-18 tires and on 80hp TT mode @72 mph =2000rpm in OD Iíll be on a steep uphill grade and will be effortless @1000-1100egt (4K-enclosed trailer)
Canít wait to try the KC38R in same scenarios.
Those tall tires have to be killing you with gears.

I am still on a bone stock turbo right now. I have not put the new one in yet. But yes the gearing is starting to be a lot more noticeable. I actually think the power increase of switching to the Hydra made this issue worse. By that I mean, it has more power at any given RPM and it takes less rpm to get to certain speed, there-go I am driving under the turbo a lot more than I ever was just using the SCT tuner.

Here is a good read on the speedo and trans shifty with regards to larger tires.

I will admit, I find that with 35s most tunes that are DD 'feel' like they short shift.

That was a very good thread you posted @akcooper9 ! I realize that "technically" the trans is still shifting at the same rpm/time/speed. However, this does not account for the extra load of the bigger tires or the now improper gearing. I guess my question becomes, is there a way to tune for this so that the TC does not lock up on a hill and not shift down? (this happens often with the Hydra, but never happened with the old SCT). I am planning to switch to 4.30 gears at some point, but just wondering if this can be corrected with tuning.
