    Default Would someone be willing to help with tuning a 2017 Camaro ZL1?

    I have a 2017 Camaro ZL1 A10
    Larger crank pulley. Larger Heat Exchangers.

    I was, finally, able to pull the stock file and I got it all setup and started making some really good power out of it.
    About 4 pulls into it, I started getting belt slip. So, I swapped to a shorter belt.

    So, I "shouldn't" be having a lot of belt slip now.
    BUT, NOW, I'm only seeing 2lbs of boost. My throttle is staying open to 83% throughout the pull.

    I just want to make sure that it's not my tuning and I need to continue to chase a mechanical problem.

    Would someone be willing to check out my stock file to my tuned file?
    (Please note, I haven't finished it yet and I've tried changing some of the tables to troubleshoot)

    Thank you!

    I'll help look at your tune (I've done a few E92's, i.e. not many)... you can either post it or email it to me.

    Looks like engine is running from MAF.

    Where do you see only 2 psi of boost...?

    I take it you can't hear the belt slipping...?

    Is there a way of verifying the belt does not slip...?

    I'm datalogging the MAP sensor
    I'm seeing 120kpa.
    In previous pulls, I was seeing 185kpa.

    I've got a new belt on. Originally I saw a lot of belt slip! It was obvious. The tensioner was bottomed out.
    I put a properly sized belt on it.
    Also, the LOWER pulley was swapped. It has the stock upper pulley!

    Yes, I have it at MAF only. I use an extension harness to fail the MAF and do the VVE. I then turn it back to the stock 4000 setting and make a couple pulls to make sure it's all good!

    Good question on the slip
    I'm not sure...

    I hear the blower "start" to whine, and then I hear the engine OVER the blower. It's "usually" the other way around. Lol. The blower makes all the noise!
