My TB and maf are toasted and with my turbo set up I would like to get a better TB+MAF
Ported factory TB is all you need. The MAF you would be better off going with an external such as a LT1 (complete plug and play) unless you get a modified MAF for your L67 TB that will give you some more wiggle room when upping the boost.
I noticed you put some numbers down for various modification levels, which is awesome. Anyone have any dyno info? If not, when do the various turbos start spooling up?
