If you attach your tune file and a scan, you'll probably find people will respond. It's hard to help if there's nothing to look at.

There are points in your scan that show you hitting over 10psi of boost. If you're running a stock internal 6.4 with a Hellcat blower, I'd be very careful how much boost you put in it. I would...

I run a phaser limiter and ANN for my Mk82. If you locked out the phaser you must be planning on running it on VE. It should start on the stock tune.

I would definitely spec out the injectors and check the data. It doesn't match FIC or Injector Dynamics data.

There are a couple of things you can try for the surging.
1. Check your scanner, you...

This video might help you too.

What plug gap are you running? My 6.4 runs 9.7:1 pistons and 16psi with no misfire issues. I run my plugs @ 0.028" gap. Still running the original coils.

I don't see any changes in the file to your timing. Looks stock. There nothing to really see with the timing in the scan because is only idling. I can say the it looks lean and there's an issue with...

22 is the closest I have.

Looks pretty normal, maybe slightly high but your idle speed is lower than what I run with a cam. I idle @ 750rpm with MAP @ 53kPa.

I did a 3.21 to 3.92 swap in my 19 Ram and just used AlfaOBD. Didn't change anything in the tune when I did it. I find AlfaOBD better for ratio changes and gas tank capacity changes. The only tune...

Glad to hear things are working out.

With cam tunes, I usually increase the throttle body airflow from 0.00v - 0.30v and then adjust the "Small Range" throttle settings to match. This can help...

Main thing will just be the fan settings for a thermostat change out. You shouldn't be getting any codes from that anyway. Just a thermostat isn't going to net you HP gains. You need to actually tune...

Nothing to be concerned about. If you look at the differences, most of them are just axis scaling but everything is technically the same.

Don't know about checking injectors with HPT but I've but I've used a temp gun on the heads to find inconsistent temps.

I have a fresh build and the ticking was very light. My oil viscosity was...

Yes, pressure goes up pretty quickly and is consistent. It will see 45-50psi @ 1800-2000rpm, 70psi around 3000-3500rpm.
I guess the thing that had me concerned was I could hear the motor ticking at...

2019 ram 1500. It's a build motor, FRP Mk82 cam and Harrop supercharger.

I do one question though. The motor has a Hellcat oil pump but the oil pressure is 20-25psi at idle once the oil reaches...

Firstly, I'd say the the injector data in your file doesn't match up with any Hellcat data I have. Not sure where your data is from but I would consider correcting it or you'll be chasing your tail...

I know this is an old post, but I was searching for anything already posted about surging. I'm dialling in a new 6.4 build and was having oscillation under deceleration. This really helped so thank...

Seeing if anyone has a stock file for the 6.4 in the new 2500/3500 Ram's or the Jeep Wagoneer please.

I'm chasing the injector data for 6.4 manifold swap. Not sure if the injectors are different...

Here's a stock 98 Viper GTS file. You'll find it's probably the same as a 2000 model.

2015+ requires a PCM unlock to perform any changes.

I'm only dealing with the GM tuner so I can't say who's check the gaps. I know the installer never gapped the plugs the first time. That was picked up by the GM tuner. So it had new plugs put in at...

Ha ha, all good. I had to confirm with the other tuner too coz he said FIC and I was like "yeah they're good" but I sent him my recommendation which is when I found out they use FI Connection.

The...

Thanks, I use Fuel Injector Clinic injectors and data usually but because of the situation I'm going off what the builder is using which is Fuel Injector Connection (Both "FIC" acronyms but...
