Until I see some before and after Dyno results, I'll take Tbrains HP & TQ claims with a large grain of salt. Also, I wouldn't want to have to keep replacing filters when using Dejabblue's kit.
When my Raider was normally asperated, I used a PR BAK, with LA Chopper pipes, and a PC5, which on the Dyno, showed a noticable increase in HP & TQ. I don't think there is any noticable difference between the PR BAK and the Barons BAK. As far as pipes are concerned, get what you like. For fuel management, I run a PC5, but the improved version of the PowerPro seems to work just fine.
