I'm thinking about going with the new HTT stainless turbo. I need help deciding which one will fit my needs best. I plan on stacking a TST w/pressure with my Smarty, studs, ATS exhaust manifold in addition to what I already have. I'm on 35's in the mountains of Tennessee and I only tow a bass boat. I'm concerned about the lag of a bigger turbo as well as the low boost codes that some people are having issues with. I only occassionaly take it down the track and am looking to be in the 525-550 hp range. What do you all think? Thanks Tac.

 

from what others are saying, id look at other turbos right now

Ii Sps 62/14.
not much lag, almost none when stacking boxes
supports over 500 in my dyno runs
cools good when towing
gives me great towing power.

 

Do IIS SPSsilver turbos take the same tuning that the HTT turbos take???
seems to be a few threads about the new HTT taking some tuning to get right???
