    Making adjustments to tune for a similar cam.

    I've busted a lifter and wrecked my cam. LS7 lifter failed... the one closest to the oil feed no less. I'm running Brian Tooley's specced LS7 lifters now.

    Going to a new cam with almost similar specs, same XE lobes as before.

    I've got a few hours of dyno time and access to a wideband, but I want to run some thoughts on adjustment direction since the cams are similar

    Old: 230/230 115+2 LSA 0.613 0.605
    New: 235/238 115+3 0.620 0.615

    I'm thinking of dialing in the WOT by having the MAF dominate in HP Tuners from 2000 onwards and making small adjustments to the MAF table until I get my PE numbers back in line to 12.8. Other than keeping a listen for any KR and timing, are there any other tables/adjustments to consider with WOT? I will do the VE tuning and minor smoothing of the MAF over the next few weeks.

    Edit, it worked, I was able to just raise the MAF table by a few percentage points until I got it.
