Thread: Ported Intake AFR changes?

    Ported Intake AFR changes?

    Hey guys I recently picked up a Rick Crawford ported ls3 intake to go on my ls3-fbody swap. Putting it in this section as its still being controlled by the ls1 pcm. Anyway tuned the car on the dyno for all its mods with the stock ls3 intake. Now that I'm adding the intake my afr should still be fine correct? I didnt change any of the piping for the maf so the calibration shouldnt be off, is my thinking correct on that? I know lower rpm ve might need to be tweaked a hair but my main concern is it not deviating from the afr at wot. My laptop is down right now so I dont have access to hptuners, this is just a sanity check here.


    thanks for the help!

    Your commanded AFR should not change.

    But the VE will now be different and in need of tweaks.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
