Duramax tuner

[gmduramax]

Hey Nick
I was looking through the library and I seen this tune
LMM08DPFdeleteHOT_06.07.08_Highboost.tun
It says high boost but is it ok to work with my stock turbo.

[Nick]

Yes it is, the high boost reference is for lower in the rev range. Peak boost has not been adjusted.

This tune was built to be able to roll into during high gear and not have it roll smoke.

Ok cool thanks I will be doing some testing ):h

Anthony,

I should have been clearer....

I mean part throttle and low RPM. If you roll up to WOT, you'll still get smoke.

See the boost tables for more comparison details.

I understood what you said I should have explained a little better.
If im going 50 then accelerate to 65 with maybe 30% throttle I see more smoke than with the 11-29-07 tune. And when WOT with the 11-29-07 I get no smoke at all, with the new tune there is a little bit of smoke.
My truck might just be :cookoo:

:confuzeld:I don't have a good explanation for you aside from possibly a change in outside conditions (Humidity, IAT, ECT, ect.). The changes between those two tunes are limited to the desired boost tables from what I remember.

I tested one after the other, so I would think the variables would be minimal. I guess we should see what other people say about it. It did feel stronger going from 50-65
