    Decision,Decision,Decision all have their Love ! My maltese,ers are running low
    Tunehouse actions speak volumes ,Jim does the tuning work himself ,its his rep on the line . Mrt has too much marketing and self promotion for my liking .
    Bite the bullet and post your results ,we are all waiting .

    the posting also went on to say "Built engine with bigger turbo…different story, but since 95%+ of our customers running MPS models aren’t running that style of setup, making fuel pressure pump modifications to provide more flow isn’t necessary in experience."
    the issue isnt with needing extra flow, the in-tank fuel pump and injectors are all matched up fine to provide enough flow, it's the fuel system losing pressure...
    but when you only run 16-17psi, and dont hit "full" boost until 3600-3700rpm, which is a complete waste on stock turbo, you arent going to tax the car that much...

    just wanted to put the information out there

    From stock, to GT3071, to substantially less modded, many lessons learned!

    Most tuners do. I wouldn't want to be popping engines every second day. It is just that some guys have a few more tricks/knowledge to get more power then others... But I know a few shops that just smash boost and cross fingers... They don't tune anymore as you can imagine.

    After my tune with tunehouse, Jim explained he does a few runs after he has worked his magic to find a "comfortable point", then he dials it back a touch to keep it conservative and safe.

    The more you chat to jim before the tune and you will be better off for it. Let him know what fuel you run than continue to run that or Jim advised fuel, what that means is he can dial in a bit better and you will prob get you some extra power

    My first TH tune had a large boost spike like that at 3000RPM but that was ironed out in a subsequent tune. It didn't settle at 19PSI.

    We dont recommend that much boost on stock internals.
    Boost may be a drug, but like drugs it can also be dangeous

    if anyone needs any help and advice, please call us 0297674545 or watch our MPS videos here
