I'm a little late to the game on this post, but don't go IPF. They barely support the product anymore and it has a number of faults in the design, power steering relocation especially. I have an LLT kit and I can't say I'm ecstatic with it.
Go with the Overkill system. This is a much better design, uses a dedicated belt (as opposed to the IPF which reuses the OE serpentine belt), better tuning, better support, better power steering solution, better PCV system. Overall, better better better.
