Hey guys,
I often get clients with cars that are previously flashed with known or unknown tunes, but as usual the cars do not run well. I first walk them thru doing a proper boost test, then fix the leaks, and then re log as usual. Here is a XXX tune log, as you can see the actual lambda bank 1 and 2 are slammed to .73 on boost in third gear.
The next log is with my 1 bar flash nothing else changed. You can see the issue went away and Im even running .1 bar more.
I strongly suggest guys who never logged the car to check actually whats happening to the car on boost... even if you bought a tune yourself. The more educated you are about the tune the healthier and happier you and the P car will be...
best

XXX tune 3rd gear pull.




My 1 bar tune nothing else changed.

 

It depends on the fuel IMHO. If this is E-85 / E-100 then let it eat (12.0 AFR isn't really that out of the ordinary for great fuel)

 

We target .8 to .82 lambda on boost depending on mods / fuel quality etc.
but .73 is def. not right.
