can someone please look over my data logs from cobb beta tune and tell me if there is any problems or red flags. My car is 2009 with cobb 2.75 intake and catless midpipe running version .360 93oct.

Thanks

The Injectors and MAF's are maxed out. Pretty typical of a tune car. I am surprised the Cobb intakes max out so quick though, they peg at about 6000rpms.

But 105% A/F Correction is OK, Fueling is conservative, The timing looks good, and no knock.

Also another quick question, when i installed the cobb intake i forgot what direction the maf sensor went on the passenger side so i put the silver side facing the passenger side, does it even matter?

From the datalogs it looks like they are working properly.

They should have a flow direction on them, if not make sure when looking at them the "Hot Wire" you can see it from the front. I also think they will only go in 1 way.

They will only go in one way on a properly machined MAF block. Also, if you were able to install it backwards it would cause the car to run horrible.

By your logs you need some 3" intakes along with injectors.

I did what Dave suggested (using his 3" pipes and ID1000 injectors) and am very happy. I'm not a tuner like some here are, but I'm GUESSING that with your MAFs saturated, even the best tuner won't be able to get VERY MUCH MORE out of your car, with that limitation in place. Mine saturated too with several adjusted E-Tunes, prior to my changeover.
