I have a T-trim upgrade. SI is rated to flow a little less and with 4 less max psi. But I have a feeling by it's specs it's underrated. They are phasing out the S-trim all together. If you do get it do the Si not the SCi because it's 3% more efficient.
You can prove that with how much you got outta the S trim!! Yea, gonna ponder it after the intercooler install
