| Today with no luck. I know upgrading the piping and IC openings along with the TBs netted a wider powerband and 30ish HP/50ish TQ gain in the peak numbers. The biggest difference was an additional 92 FT-LBs @ 4200RPM. Seb's dyno post of a customer's car Greg's explination I personally passed on the 58mm TBs when I did my build because I knew I wasn't getting the 2.5" pipes and IC's any time soon. If those upgrades are on your list in the near future, I would definitely get them. Otherwise, IMO, I'd pass. Again, this is speculative, as I couldn't find a dyno to show the differences of only changing the TBs. If you don't have one, I would get a Selin Dual MAF translator, and pick up a second MAF. Definitely want to give those turbos all the air they need, and a 2 MAF system is the best way to do that.
