    05 Silverado tune check

    I am tuning for my 05 Silverado. Everything is stock except a cam motion "Lil' Lope LS Camshaft (216/224-108+3)". It is a 5 speed manual. I did my MAF tuning and that is great, but I have started my VE Tuning and want to make sure I am not making a ton of mistakes. If anyone could offer constructive criticism that would be awesome. Let me know if any addition info is needed, thanks!

    Need to smooth out the VE table. Those large mountains will make the PCM calculate the air mass incorrectly and your timing will jump around.
    Plus no engine will ever have a Fuel table that looks like that. Should be smooth from cell to cell.

    Does this look better? Are there any other issues I should be aware of? I think my table got all messed up from me trying to ballpark myself into the correct spot

    Its better.
    Also your spark low octane table is higher than the high octane table.
