Piasini flash and DP back fire

[ccs70]

I guess this is a question for Tim or anyone with the Piasini flash and a DP:

Like everyone else with a DP, I'm experiencing back firing... and I don't like it. I'm getting the Piasini flash soon and my understanding is that it will lean out the fueling somewhat. Will the Piasini flash do away with the back firing, or is that too much to hope for?

I have the cp-e catted DP and a reworked K04. If the back firing doesn't disappear with the Piasini, there will be a heat wraped DP up for sale shortly...

hey so far i have no complaints about back fireing i just had the midpipe installed and so far so good the few that have a DP and the tune have not mentioned anything to me about it

[ccs70]

Okay, thanks Tim, that sounds promising... Anyone else that can share their experience?

Is it true that the Piasini flash is leaner than the stock map? Do you know if this was a concern when the flash was developed?

By the way, have you had any cold-weather experience with the flash yet?

There are only a handfull of guys runing the tune in the U.S

Yes the Piaisni flash is leaner then the stock map not in aa huge way though.

Yesterday night it was 35*F outside she ran great.

Thats because most people like the backfiring...

I don't think the backfiring will cease...reduce yes, but not totally disappear.

What kind of BOV/BPV are you running ccs70? Is you are VTA, then thats where your main source of backfiring is coming from.

true !


lol i dont get shift afterfire at all some small poping at very low rpm from the back pressure

I'm running the forge bpv... however, I'm experiencing a boost or vac leak that I can't find the source of. This results in a erratic idle. Thought perhaps the back firing and boost/vac leak where unrelated, but I suppose that a boost leak easily could result in back firing.

No backfiring here either, alls well

Yes, a boost/vacuum leak will cause major backfire!!!
