hi VF...
the si, is the unit rated for more power and has a higher efficiency @ 78%, it also has a CFM of 1150, just 50 cfm off the T trim race units....
the sci trim is @ 75% effieciency and has a CFM of 1050cfm......
The Si is a better unit and can peak with higher boost pressures.
Really interested that you guys used the SCI rather than the Si Trim unit....
im guessing at lower boost pressures they perform similarly anyway....However, both producing 10psi the SI trim will make more power as its flowing more.
you may want to update your add, as their is no SQ trim unit..... just SI Trim and SCI trim.
