I'll vouch for the Jet for sure. Works great in my SSEi, and it'* actually been getting stronger in the week I've been running it as the PCM 'learns'. Do your intake, exhuast, and 180° Thermostat FIRST, as the Jet Stage 2 chip is tuned for those mods. I ordered mine from Hector. Great price. Allmachtige just ordered his and hasn't got it yet, and Turtle is also running it. Has been for quite some time. Allmachtige is running the Superchip currently, but is changing, so he'll be able to give us a direct comparison between the two. The superchip is a full swap, and the Jet is a piggyback.
As far as your intake goes, I should know this weekend if the ADTR intake fits a Series 1. If it does, you're in business.
