I'm leaning with the Maggie because it's a relatively known kit as of right now. Several tests have shown ~500 RWHP on 6 psi of boost and completely safe for the car. I'd like to see what the TS companies are coming up with as well as the centri' guys. They're air-to-water but we know the LS9 intercooling drops temperatures to ~140*, and it's my understanding that set-up isn't nearly as efficient as a Maggie set-up.
I'm always open to new, unbiased, information though
