A 2015 or newer Ram 1500 and the 8HP are outside the current offer.
MDS delete, VVT, airflow, spark, NAG1 and RFE shift work for the 2005–2014 Hemi range. That includes the 5.7, 6.1, 6.4, Charger, Challenger, Scat Pack and Ram 1500. Cars with the NAG1 transmission have a second computer for the shifts.
2005–2014 only. This hub covers the 2005–2014 Hemi controller families and the 545RFE / 65RFE where those tables sit in the engine file. We do not have a 2015+ controller or 8HP tuning procedure, so we cannot take a Full Custom order for one yet. Email support@tunebible.com with the year, engine and transmission if you want us to note your interest. We will not promise a date. You can still send a 2015+ file for a free Tune Report: it’s a written review of your file and log only, with no standard turnaround.

Find your computer: NGC, NGC4, GPEC, 2005–2014
The year gets you close. The controller name in the file settles it. If the two disagree, stop and identify the file.
| Year and vehicle | Controller | Transmission | What that means |
|---|---|---|---|
| 2005–2006 5.7 cars and trucks | NGC | 545RFE or NAG1 | PCM read. NAG1 is a second computer; RFE tables live in the PCM. |
| 2007–2010 5.7 / 6.1 | NGC4 | 545RFE or NAG1 | Same split. The year does not tell you the transmission. |
| 2011–2012 Ram 5.7 | NGC4A | 65RFE or 8HP | The truck is NGC4A, not the GPEC used in the cars. The 8HP is outside this hub. |
| 2011–2014 cars, 5.7 / 6.4 | GPEC (listed as GPEC1 or GPEC2 depending on the source) | NAG1 | PCM read. The shift schedule is in the separate NAG1 TCM. |
| 2013–2014 Ram 5.7 | GPEC2 / GPEC2A | 65RFE or 8HP | The controller name in your file settles which one you have. Identify the transmission before following its tuning instructions. |
A 2011–2012 Ram 5.7 is NGC4A. A 2011–2014 car is GPEC. They are not the same file. Do not write a car calibration into a truck because the engine is the same size.
2015 and newer. The read can happen before a bench service; the write waits on it. 2018 and newer also needs the Smart Access Cable before a read or a log. This hub does not sell a 2015+ write.

What you need
- HP Tuners interface and credits for the modules you write
- A read of the PCM; a NAG1 TCM read is separate and confirmed first
- A log that shows the complaint

Questions
Mopar questions
Will turning MDS off fix a Hemi tick?
Turning MDS off in software does not replace a failed lifter or repair a worn cam. Tell us whether you want a calibration change on intact hardware or have already installed delete parts. Send the cam specification and what changed. We match the file to that hardware and leave MDS alone unless the build needs a change or you request one.
Can you tune a 545RFE or 65RFE?
On the 2005–2014 integrated NGC applications, the 545RFE and 65RFE tables sit in the engine computer. Their tuning is included in the $199 engine file where those tables are in that file. The NAG1 uses a separate transmission computer. Include it in the order notes and we confirm coverage before work starts.
Do I need HP Tuners credits for a check or a revision?
Reading a supported controller and recording a log do not consume tuning credits. Writing requires the right license on your interface. Revisions based on the same licensed vehicle, module and operating system do not need another license for every write. A replacement module or changed file identity needs a fresh licensing check.
What if an engine-only read asks to license the TCM?
Send the module list and the prompt before spending credits. A fresh engine-only read with the separate TCM set to Do Not Read can avoid that prompt. Use that route only after confirming the job needs no TCM changes. Keep the complete original read.

Sign-off
Final check-off before delivery
Compared against our 3 million+ tune values, with a final check-off by our lead tuner.
A cam, headers, boost or E85 changes the air, fuel or spark model. The $199 Full Custom engine file covers them on the supported 2005–2014 5.7, 6.1 and 6.4.
Full Custom is remote work on your file and log. We send the engine file; you flash it with your own HP Tuners interface and credits. A local shop is the right choice for a mechanical inspection, an install, a dyno measurement or a hands-on diagnosis. NAG1 is a separate transmission computer and is not in the $199 engine file. We confirm coverage before work starts.
