    I'm looking at this thinking you have some work to do if you want everything to work correctly.

    1. You need a 2 bar MAP sensor, minimum. I know from your message on tech you want to step up to 12...

    Lean Spike on Hard Acceleration

    It's been quite a while since a tune had me stumped, but here we are. I am tuning a customers 2010 SS Camaro LS3 and everything on the MAF air model is absolutely great almost everywhere. I have the...

    I just noticed in your log, that the MAF is still reading airflow. It should say zero. Unplug it if necessary, unless it has the integrated IAT. If this is the tune file that was in the PCM when...

    Okay, had a chance to look at your tune and scans. Are you using a rail type fuel pressure regulator? I know it's a swap, so have to ask. If you don't have a rail type fuel pressure regulator, then...

    Don’t mess with the injectors if they are stock and on stock data. Knowing now that you have the dual VE tables of the early computers (non 0411) then 5FDP is absolutely right. In SD the computer...

    I’m not on my laptop right now, but venturing to guess.... do you have the MAF disabled? Changing the VE won’t do a ton when using the blended model (aka both airmass models, MAF and VE). I’ll bet if...

    Awesome. Just remember that when the IAT shifts around, the numbers can be off, as in they might match when you tune it, but they won’t the next day, etc.

    The idle calculations are different from...

    Larger cams don’t tend to respond well to more fuel. It’s fairly common to have leaner readings at idle, especially if you have a lot of overlap. Since you have headers too, the delay to the O2’s is...

    You'll need the powaaaa for that, or some skinny old bald tires. Make sure all the TM is off, and of course, optimize the tune for more low end torque.

    Another note for the "fireball mode" as...
