well, it seems the problem is the gas... im looking into mixing some vp ms109 to my tank, 5 gallons and mix it with the 95 pump gas we get here in panama, perhaps this might solve the problem. ill let you guys know.

Try not to push the gas panel down 1 shot, just push it down slowly when up shift. The throttle position may affect the AFR to be too rich till it misfire. At least this is what is happening to me. Good luck.

It happened to me too with the DTM on 4th gear. I added the catless dps and shortly thereafter a tune... A week later I got the DTM when going WOT... There was definitely not enough time for tuners to do proper testing. I am troubleshooting my issues with my tuner and see what happens... I read somewhere here that LEIB http://www.leib-engineering.de/ knows how to fix this?

Ah what do you mean not enough time. They all had time. Don't premature put out a product if it's not well tested. Yes they all had time but some chose not to fully test out before making claims.

I did but for the most part. But I've spent part of march offshore. All of April offshore and by the 27th of this month 93% of this one too. I'm only saying they had plenty of time to fix things before being released. There are a couple things that have to be sorted out w mine. It will be addressed when I can get home.

no, the vp did help, the car runs smoother, but the problem isn't the gas, its the tune itself because i keep getting the error at high speeds, high on the rpm in 4th and high on the rpm in 5th.. cylinder misfires across the board.. I'm upset and disappointed to say the least.. perhaps I'm going to go back to stock.

It seems that a lot of the cars with catless downpipes and full tunes are having this issue.
We have to go to the source (BR). There is couple parameters that most local tuners are not compensating for and it throws a DT due to air/fuel mixtures. Either Bruno or tuners in the States need to spend more time on fixing this before releasing to the public. I know couple people with ESS tunes and no issues there since it was fully tested and revamped by ESS after coming back form Europe.

In my opinion is all about the timing & fuel mix, so I'm using the jb4 to counter back these issue. On my stack with JB I add boost to lean off the fuel & meth to compensate the low Oct of fuel used, that result in extra power. Ya I know some wouldn't want it that way bcos they wouldn't want to run meth & add boost on top of the tune. But in my case I didn't gain any faster in the tune alone, u can feel that the car is faster but I can tell u it is not. The mid range extra TQ is the thing that let u feel the car is faster but once it pass 4+k rpm the car will just slow down or rather I would said not pushing anymore. My case may or may not be the same as others but I can say most of us have about the same issues. |

So the same issues have appeared it sounds like. WOT causes dtmal, limp mode, misfire on cylinders..fuel starvation issue..

This is not the case if Andy is correct with his mention of the fuel mixture climbing all the way to 10:1 or richer, and that causing the misfire. If that is the case the high pressure fuel pump is able to keep up obviously, and just a rewrite of the code should be able to correct things.
