Fairly soon (definately before christmas), I am going to be ordering a Mongoose SQ trim kit. I am going to get the polished kit, with a boostpipe. A few questions...

Do you think i should get any other gauges when im ordering the kit (a/f and boost)??

What is a mini race bypass valve, and do i need one??

How many pounds should the sq trim kit with a boost pipe put me at??

Will i need any other parts/pieces other than the kit, and possibly the gauges??

thanks guys
