your idle MAP is much too high.

Take a look at your BOV.

switch off sensed MAP

Try this out and see if it helps with your issue on it pushing.

Looks like a BOV problem. At the end of the run the throttle blade goes back nearly to idle position. It's not like it's hanging open.

[Hemipheen]

ok i will try this and report back if it helped or not i will also double check the blow off valve.

[edcmat-l1]

The D1 kits come with the little generic BOV. You need a big "pro" style one. I never use the ones that come with the kit. I always upgrade to a larger one.

i forgot to mention it does have the big red race valve installed

If that's the case make sure it's open at idle. Should be wide open. Id it's not you may need to pull the spring out of it and cut a spiral out of it. That's not uncommon to have to do.

For the price, that seems pretty sad

ok i tried your file and i feel it idles better and part throttle is better i think it got slightly better but throttle still gets stuck at wot.
I also double checked the blow off valve and it seems to be working properly its wide open at idle and closes when i blip the throttle.

Do you have the stock unmodified tune file for this?

[Hemipheen]

yes i do here it is
COMPLETELY STOCK TUNE FILE.hpt

[edcmat-l1]

I don't know what it is but there's a whole bunch of shit I'd put back to stock and go from there. Lots of TM stuff, DFCO, several things that all could be contributing to it. I haven't seen one of these do this in a while. Used to see it a lot more back in the early days of Dodge tuning.

See how you go with this.. Based on the tune you posted in your original post... Your tune needs work but this may solve your throttle issue.

What about the throttle hang when it's under 3600 RPM?

To the OP. Who is doing your tuning? Have you considered putting most of the file back to stock and starting over with the basics? Injector data, P ratio axis change for boost, MAP sensor values, etc.? That's what I would recommend doing. There's way too much shit changed that collectively can be causing you problems.

When I have problem cars come in my shop, ones like this, if the customer does not have the stock file these always get flashed back to stock using a factory tool. Then we start from scratch.

actually removed that post... not going to be posting here to help anyone anymore.. Think you guys are in good hands

[f.creek-ranch]

Wow…my Google search says :

Voluntarily, unsolicited

That’s what it is.

[veeefour]

Not acting like a smart ass...even tho I frequently do...all them files no good

[edcmat-l1]

Sounds like I missed some drama or something.....

[Hemipheen]

i had some time today to mess with the tune and found that turning off sensed map fixed the throttle hang issue and drivability is alot better.
but still has problem where at wot it seems to be using the min spark table.
