Sorry, I'm new here. Just got Eurocharged Tune first so that If I throw any codes I can check and clear them when adding bolt ons. ( intakes, throttle bodys, exhaust). I was going to do the TB and the NW single but now I wonder about the larger TB. Might just keep the stock TB, nw single, and now.... Sprint Booster! If anyone with an SRT6 bought one and thinks that their car is too responsive, PM me and cut me a deal!
