    First and second are the biggest changes but accelerating from a cruising rpm should feel better too. Maybe check your hose clamps for boost leaks.

    Which map are you using? Also, if you haven't already, I highly recommend a K&N panel filter. The tune with 93 octane and the K&N is pretty sweet!

    I live in Cali so best gas I can get is 91, 91 map stage 1 v101. I'll skip the filter since I am probably gonna get the mountune or cobb package at some point when the get CARB figured out.

    Just installed the Stage 1 AP a few days ago and I must say this car just went to another level. Now 6th gear feels the way it should, no more down shifting for that easy pass on the highway. Can't wait for when we can finally make 300whp...:D

    Count me as another very satisfied Cobb AP customer!

    4 peak hp would normally make anyone say whatever with any other tuner. I see where it does fatten the torque up, but what's it gonna take to see some real HP numbers? I guess this is a characteristic of small displacement with a turbo.

    No, its pretty much just the small turbo.

    Cobb stage two gets it up around 210 whp but that's intake, intercooler and piping.

    With a downpipe upgrade we might see 220 or a little more but I think that is about all we will get.

    Once you swap the turbo for something bigger, the next bottleneck is the fuel system but ATP has a car running around with 264+ whp with an upgraded turbo, intercooler, intake piping, downpipe and tune.

    With different turbos and a more mature tune, 300 whp should be easy if the fuel system can keep up.

    I'm guessing they use the Cobb tuner. ATP's stuff looks really nice to me compared to others I've looked at.

    When will people realize that peak hp dyno queen bragging #s aren't the be all end all factor in performance.
    We have a very light car. +25 tq for is is probably closer to +35 or +40 in a fost
    Our peak tq jumps 25 or so with just a stg1 flash and a panel filter. That's quite boss.
    Our intercooler is a bottleneck on the gains above 4k+ or so, as the dyno curves mate back up again around there
    The stage 1 with a filter does many things other than just peak increases...
    -low end peak tq is higher
    -peak tq comes on sooner and stays longer
    -throttle response is snappier
    -tq limit removed in 1st and 2nd (probably the biggest change)

    Once you pop an intake and fmic on, you see gains accross the entire band, not just before 4k or so
    I think you should check out the stock, stg1, stg2 dynos that "the smoking tire did" before you discount any stg1 and stg2 gains

    Also, going back to peak #s, a 2012+ civic si can use the rbc intake manifold from a 06-11 si engine to gain 10-12whp peak... above 6700rpm... below 5k you lose hp and tq and the car winds up being slower in a race even though it's peak dyno is higher...

    Useable power trumps peak dyno power every day

    The car already has plenty of torque, but I realize more definitely helps for fun day to day driving. It made a huge difference on my 06 GTI to upgrade to Revo. I was just trying to figure out what seems to be holding back HP gains. So it sounds like the FMIC and intake make that difference, but I'm sure the engine size and turbo size are matched for useable torque for a much more fun daily driver. I'll be doing a tuner first, but I kind of want to wait and see what Superchips and Revo do here in the US.

    Please remember that horsepower numbers sell cars and torque wins races.:)
