    Car sounds rough

    The engine sounds rough, only 18k miles, oil changed recently fully modded with meth but keeping it on map 7 for now and I push it once in a while , however I ran it once on high boost with 15 ohm board with out meth flowing , safety wasn't connected God saved me becaus I was doing a log at the time and I've realised, What can it be ? can I try new sparkplugs ? Should I do engine diagnostic ? Thanks

    Hmm, do you have a BT? Check for fuel pump/ injector codes... Any hesitation or stumble while driving?

    Hpfp can go 5 miles after being replaced lol, sounds like a fueling issue... I'd fund some1 with a bt and check for codes that might not throw a cel

    Maybe you should hide the coke from your car for a while.... it may end up throwing a turbo or two though.

    If you have meth, your getting some drip from the nozzle. mine used to do that when it was installed, i since then have moved the checkvalve to pre-injector. solves that problem as well

    they had my car for a week. they fixed it. all new parts and the latest software ( this was back in May i guess since the vid is from march 31st)
    not a single problem since


    out of all the vids I've seen, mine is the worst.

    Ahh I had it before I had meth and the middle of summer it helped but not as much as meth... I'd say once you go 15-16 plus psi I think it comes in big time in terms of holding boost
