    My HFP felt way more responsive when i ended up removing it to sell the car... it was the only bolton i add w/ stock tune.

    Don't they say the rbc intake does nothing aswell? Nor the zdx throttle body?...

    I'll be ordering my u-tune here shortly. I am running skunk 2 cai, p2r tbs, invidia N1 catback , and full race downpipe. What kind of power should I expect to gain with this tune. I really hope skunk 2 did a good job with that cai

    RBC sacrifices torque in the mid-range for hp in the upper range. ZDX provides a bit more hp in the upper range.

    If you are staying NA, don't install an RBC. If you are going FI, install one.

    Vit says usually 200ish to the wheels. For comparison, stock is in the 165-170 range to the wheels.

    I think I just went into some sort of spiral following links in the threads and they all talk about the same thing. I really wish I had the free brain capacity right now to remember all of these discussions.

    He posted a new rbc dyno on that thread without any losses that I see. It's all gains despite him saying in the other thread that you'd lose hp/tq w/rbc setup. I quoted it asking for an explanation without a response

    I chimed in on the rbc debate. The best i can tell from looking at the graphs is no loss. The one that he posted claiming loss of power was unusual.

    Have you checked out Vitviper's blog?
    He has lots and lots of useful information and would most likely answer the questions that you have.
