Hey ya'll, I have a 2007 Civic Si FA5 and I'm in need of assistance to fix my tune. At the moment, I have the 'Completely stock, tuned' base map tune calibrated in the car however I still seem to be having issues with losing power. I'm not familiar with the term but to describe it; I did a pull from 3rd gear between 2k-3k rpm to redline, then it would seem as if the car is picking up acceleration pretty quick according to the gauge then will lose power a little after 3k rpm then slowly gain more speed. I'm attaching the datalog that I did the other day. Any kind of assistance you can provide is greatly appreciated.

Hey how's it going. For now, I would recommend not doing anymore aggressive driving until we get this sorted out for you. The fuel trims are almost maxed out trying to add fuel and it is very lean in vtec.

So you're running the stock tuned file on the MAF sensor?
