    Same power more mods?

    So I got tuned about 8 months ago made 288whp on a mustang dyno car was 2013 Evo x GSR with drop in filter and test pipe back.

    I got tuned today same tuner same dyno but different car 2014 Evo x GSR with Ams intake/ uicp/ licp / inter cooler/ hks short down pipe/ ETS test pipe/ invidia q300 catback. Made 295whp...

    Really confused to why I only made 7whp more?

    1. Different day meaning different temps, humidity, etc.
    2. IIRC the short downpipes don't really give you much of a gain.
    3. Different car, not all evos react to mods the same way.
    4. You shouldn't be focused on peak horsepower but look at your midrange and generally your powerband as well as how your car feels at the end of the day.

    Yeah, you're looking at the numbers all wrong. Post both graphs. You may have only gained 7 peak whp but maybe 30 or so whp later in the powerband, in addition to all the factors boosties said.

    I mean the dyno graph of your old car, where you made 288whp.

    I can see that your tq curve improved from 3100rpms to 5300rpms, in that range you also gained about 5 to maybe 20wtq.

    as far as whp goes you didn't gain that much but there are gains from 5100 to redline. also your midrange (3650-5300) looks buch better than your old tune. Your holding power better up top your new tune and mods.

    Like me and jpsevo said, forget about peak hp numbers they're just there for bragging rights. In my opinion your new tune has better usable power and should feel better than the old.

    Thanks for the info! He was also saying something about what I gas I used. I filled up on shell and he said costco gas is actually awesome and I'll have less knock. Input?

    Because the more ping if I'm correct you'll get from Costco fuel, hopefully I used the correct term, which will get you closers to detonation.

    Shell/Mobil/Chevron/76, I've ran Costco fuel but I didn't go balls out while filled up on it.

    I would only fill up with Costco gas if it was the difference between putting that in or pushing your Evo to the next gas station. Other than that, no.

    Chevron/ Mobil never done me wrong. I've put Shell a few times too and didn't really notice a diff. from what I usually put so I guess thats good.

    But Costco gas, nope, thats like feeding your newborn dirt...if not worse.
