You are going to have to install the bcs at the place you get it tuned. You CAN NOT drive it with your current map (no you cant just be careful or "stay out of boost" it wont happy, you will overboost every time you step on the pedal). The wastegate duty cycles have to be lowered A LOT for it to run. Luckily it takes like 5 mins to install and only requires a wrench and some plyers (or atleast thats all my grimmspeed one did).

Other than that, those are shitty mods to work with... I'm with Matt, I hear good things about S&R...
