Can we please get a tune that doesn't modify transmission line pressure.

Diablo's 93 tune with the increase line pressure for quicker shift's doesn't work great.

1. Light Partial throttle sometimes doesn't shift (holds too long) until 4+k causing unattended engine load to fuel ratio to be incorrect, too much load for the amount of fuel. It's causes pinging when it shifts suddenly.

2. Crisp quick shifts while cold, but becomes sloppy and harsh at operating temperatures. I rather have a delay shift than harsh slip clunk feel that feels like it a broken transmission mount.

3. Holds RPM's high after a up shift and doesn't release tension on the transmissions, almost like a transmission brake thus causing a harsh release when it does drop down to normal.

give this a shot

Mikel,

That worked like a charm! Thanks so much for taking the time to respond, but even taking it further and customizing a tune! I wasn't expecting that level of support! Kudos to great service!

Thanks, Anthony

glad to hear it.

My 2012 Charger Rt max has the same shifting problem. I have the 93 oct pref tune on it. and seems like the tranny is shifting before it needs to? would this be a possible fix?

I'm having the same issue with my 2012 Challenger R/T. Can I get a modified tune also? Attached is my current tune.

Thanks,
Chris

there is no shift firmness in the tunes for the challenger...nothing to adjust.

I think I'm have the same problem on my 2013 dodge charger

I just got my tune back from HemiFever and all is Awesome he adjusted the partial throttle upshift which helped some . but im still having issues with the Trans Shift on hills and wot it is almost like it is lugging/ or shifting way to soon at low speeds 1-2, wondering if there is a way to adjust that? if that would be the firmness fix or something else?

1-2 shift can be raised to personal preference at several throttle % points vs rpm to get rid of the lugging.

shift firmness is adjustable

My 2011 ram seems to have the same issue. I just finally got my Trinity switched from my Camaro (sold and no support for the ZL1) to my Ram 1500. But it seems to hesitate on the 1-2 shift under 1/2 throttle or more. At slow speeds it shifts fine. I am only using the 87 performance tune as we don't have 91 around here and feeding 93 to one vehicle is enough for me. I usually buy 89 fuel. It also seems to hold the shifts a little to long. But it does seem to be quicker responding and have much better acceleration. I can post up my last tune written tomorrow after it comes back from the dealer for recall work. I always un-marry before taking anything in.

Thanks,
Lucas
