    how much gains, really.

    I had talked to the guy at my local performance shop about bolt on mods before, and he told me that a vehicles computer will automatically adjust for up to 10% gains above stock horsepower. Anything above 10% the vehicle would need to be tuned in order for these mods to be functioning at their potential.

    My 01 Blazer isn't anything crazy, but I really have no clue what my "mods" have added HP wise if anything.
    Here's what I have done:

    Iridium plugs

    Airaid cold air intake (part#200-108)

    Helix Power Tower throttlebody spacer (part#43015)<- this was on it when I bought it, and I have read on here about how they hurt power on these engines. I have tried to remove it but could not find stock length studs for the throttle body

    Dynomax Super Turbo muffler (part#19331 I believe)
    2.5" pipe from muffler out the back

    Magnaflow high flow cat (part#54306)

    Would these add ons bring me a gain of 10% over the stock 190hp? I am not looking to clock the best quarter time or anything like that, I am more just wanting to know and learn if weither or not the things I have done to it were beneficial at all or just a wad of money down the shitter. Also, just wanting some input if I would need a tune or if it's good to go as is. My next goal is to make a heat shield for my air intake because it pretty much sucks in all the hot air from the engine which can't be good for anyone.

    maybe, but you definitely don't need a tune yet. I would if you decided to get headers or an aftermarket ignition.
