Default First log with my custom exhaust *ADVICE*

I hope I am posting this right but from looking at it and I know very little about tunning thus far so bare with me but it deffinetly saw over the 17.5psi that ACN stage 2 cobb is suppose to reach. THe car honestly felt sluggish and maybe it was me being paranoid it actually felt like it was hesitating to while doing the pull so I let off before redline. I hope I logged enough to get some feedback on what I need to do or how soon I need to get a protune. Just let me know guys thanks.

Did you reset the ECU or disconnected the battery just before logging? The Ignition Advance Multiplier is sitting at 0.5 so you'll be down on power. You'll have to drive a bit (near 0psi boost) to get the IAM to rise to 1.0.

The Boost curve has some oscillations in it. I think I saw your exhaust thread...you have a Magno-flow cat in there correct? Doesn't look like the OTS map is a good fit to your setup.

yeah i got both my ap and ecu back from coob wednesday night installed the ecu started the car to make sure it ran turned it off and installed the ap and flashed right to stage 2. I have dirvne the car about 35 miles so far. The IAM number has been mentioned by a guy daemon on IWSTI too. I was wondering about that number. My biggest concern was the overboosting. But there was no knocking but with the IAM at .5 daemon said he was not suprised.

And yes I have the magnaflow one.

You should log TD integral when you get around to tuning your boost.

You don't need to log KC since you have already logged FC, FLKC, and IAM.

Unless you are tuning your intake, you don't need MAFv either since you are already logging MAFg.

I wont be doing any tuning being that its a stage 2 cobb map thats just not right to edut that. Not saying that you were implying that its just that I am so green when it comes to tuning I am afraid to try and create my own stage 2 tune

Well, you are going to have to get someone to tune it. Watch your Boost and WGDC go up and down.

BTW, this is the opensource forum. You probably should have posted this on the cobb forum. Maybe cobb has an OTS map for a turboback.

stage 2 is an exhaust map. I just posted it here because open source guys seem to know their logs really well and I wanted to see how the car was running since i know nothing when it comes to tuning

Oh. I didn't know that.

Well, you can try to go one size larger in restrictor pill. That will help. You will probably want to do that anyway when you get someone to tune it since your WGDC is really low.

My personal preference is to select a restrictor pill such that WGDC at target boost is between 50 and 70%. That gives you flexibility to allow compensation by IAT and atmosphere to work correctly.

Anyway, before you change anything, ask your tuner. They may have different opinion.
