Cold surging?

[Agent47]

DRD tunes, truck surges forward when cold whistle tune active and inactive. Is surge harmful? Can we make it go away

I'm sure DRD will fix it. I'm motorops tuned and my truck surges while cruising on the freeway. My truck has been tuned for 40k. unfortunately motor ops isn't as easy to work with.

It does it only when it’s cold though

How low are you talking? Like below 500? Does it seem like it's going to die?

Were only talking about a specific tune right? Does it do the same when switched to another tune? I assume the exhaust brake setting need to be adjusted in the tune, as the exhaust brake is what causes the whistle. Might be wrong though, have you reached out to DRD?

Sounds like its creating to much back pressure.

It does it in whistle but also in normal. He said it makes sense that it does it in whistle because the tune demands the turbo engage to make the tune happen


I don’t understand why it happens when it’s not in whistle
