  1. Hi there my v7 is popping/backfiring at idle. It more sounds like a miss. But runs extremely well when driving. Idle rpm stays at 1.5-1.8k. And idles quite smoothly. The pop sound is definitely coming from exhaust side. Have replaced IACV and gasket. Car hasnt been started in 6 months, however now it is on low boost tune atm. Because of this issue.

    Any one else experienced this before?

    Injector latancy can be adjusted in stock ecu, and fuel pressure isnt monitored by ecu iirc

    Sochi hates subaru tuning. 9 times out of 10 he'll say no.

    I'd have a chat to raijin, he's bloody good, and a damn good price

    Oh I see now haha. He (soichi) sure did cut me off in the emails!

  3. Oh true? I will try hit him up and see where he got his tuned. Can I just adjust the fpr to the injectors specified pressure and itl be fine? I havnt driven the car yet. But just waiting on a few things then tune

  4. Ohk so ive just been told by St Hi Tech that they cannot do an ecu reflash for me, with the the mods I have. Which are:

    Master power 545r

    Hks 660 injectors

    Tomei fpr

    Deatchwerks pump

    GFB ebc

    Full custom twisted exhaust manifold

    Fmic

    Tial gate

    Tial bov

    Do I actually need an aftermarket ecu for this?? Because my wallet tells me I dont...

    help/advice/knowledge appreciated!!

  5. Yeah just got sinco flanges. Tbh I just wanted to make something that looked cool haha. Well might try shoot for something closer to 300kw without getting my hopes up. Oh true about the flexis!? Ohk well I hope mine will be alright haha. Any recommended tuners?

  6. Cheers for your imputs guys. Ohk I didnt know if the stock internals could handle 300kw? And joker yes I plan to fix that intake haha just thought Id take a progress shot. Yeah wish I just stuck to stock location. It was a biiiiatch trying to fit that turbo haha

  7. Ohk so im feeling abit dumb at the moment, but im in way too deep to back out. I am fairly new to subaru and went and bought a stock v7 sti. After a while I decided it wasnt fast enough/lost its puff, and being a fabricator thought that it would be sweet makeing all of the exhaust system aswell. however now that im nearing a tuning date. Im beginning to wonder 'was it all worth it?'. With a power figure of 250kw atw in mind, have I just gone and wasted money on stuff that was not necessary?

    My power mods are as follows:

    Master power 545r

    Tial 38mm

    Tial bov

    HKS 660cc injectors

    Custom sch10 exhaust manifold

    Custom 2.5" uppipe

    Custom 3" exhaust

    Tomei Type S fpr

    Deatchwerks pump

    GFB gforce 2 ebc

    Fmic

    Thats what I can think of off the top of my head. Some advie and/or criticism would be appreciated!
