in my last post i mentioned that my truk reduced engine power when i installed my BBK throttle body, but i am planning on installing a magnacharger next week. so should i just hold up with that BBK and install the radix with it or will it still reduce engine power as usual. 04 denalli with FIPK,mass air sensor,and a magnaflow muffler.

 

Hey man I was just like you I bought the BBK 80mm throttle body and put it on my truck before the blower and it hurt performance. So I put my throttle body spacer back on with the stock TB and it felt a lot stronger. When I went with my procharger I put my BBK back on and it helped with performance.
