    Ok boys and girls, I'm looking for some help. Now that my suspension is up to handling the power my car has stock, its time to turn up the wick!

    Keep in mind that I daily the hell out of this car. I've got over 5k miles in this year since the snow left in April. So my goal is great power, with the ability to pull up to the pump, fill her full of 93, and drive wherever the hell I want. I don't need to win the highest hp award at the dyno shop, just good reliable power. Car is stock now, besides the borla cat back. She put down 613hp and 615tq last fall.

    The first of the week, I should have some go fast goodies in the mail too. I've got new-to-me ARH long tubes and an off road x-pipe on their way. But I want to add the rest of the bolt ons and get it all done and tuned in one shot.

    Let's add a pulley to it, and plugs if needed. On some fresh factory motorcraft plugs now. 2.4 or 2.6? I'm sure that would mean idler and tension swap too.

    I really want to do a PMAS intake too. They appear to be easier to tune and I hear have a better maf signal. I'm assuming being limited to 93, the 129 would be all I'll need?

    Need a throttle body, and I'm completely lost on that subject. I've done tons of reading and am still all turned around on it all. Not that I'm afraid of a big monoblade, but I daily this, and cant say I'm excited for drivability issues. Let's just say that the car should have 4.10s in it pretty soon too. Not sure if that helps keep a mono in play or not.

    Now that should leave the type of tuner and who to use to do it too. Ngauge in the dash? X4? And who to tune it for me?

    Should I piece meal my shopping cart together, or find a place to do it all for me in one shot?

    Definitely appreciate any and all help from you guys. Everyone has been very helpful so far!

    Thanks
    Brian

    I’d lend myself to your tuner for specific brands but I think you can easily safely make high 600’s easily with 93, 2.4”, 65/67/69 dual TB and those exhaust upgrades. I’m sure BJ wouldn’t steer you wrong.

    Contact Van and Revan Racing and order his 13-6 Kit and knock out everything you mentioned and have outstanding customer service for any questions. With the ARH long tubes and that kit you will be very close to 700 rwhp. Tune is Lund and also Top Shelf customer service. I have the twin blade TB and daily mine with the exact setup. The 13-6 kit will take ya about 90 minutes to do the entire install. Installing the Long Tubes...good luck. Hard job even with a lift and all the tools.

    1. Find / decide on a tuner.
    2. Discuss goals / endgame for the car.
    3. Shop for mods based on discussion..

    That's one nice thing about Venomous tuning, he'll go over all that with you.

    No real goal for the car. I could care less about hitting a big number on the dyno. I want a car that pulls like crazy on the street. I'd rather drive a car with 680hp that goes like hell, than a 750hp car that goes ok, or is numb down low or something.

    Ultimately I have no plans of pulling the engine to put rods in it. So unless I find a ported blower to swap on or something, or maybe cams to make the idle pretty, I realistically wont have any more performance mods planned.

    JMHO For your goals, I would just purchase a package with matched mods and a tune with a tune device from one company. VMP, Lethal, and Revan come to mind. BTW, Keep the cats or go off road H.

    Xpipe is an off road without the cats. I have a feeling I'll have to put the stock mufflers on to tame her down some. I think she will be pretty throaty with the ataks and no cats.

    ARH long tubes, X-pipe and no cats, and stock mufflers is freaking loud. I had to reinstall the cats and now it is perfect...for me.

    Thoaty no, bad raspy, probably.
    4.10s and LTHs with off-road exhaust.
    If stuck on pump 93, how many miles realistically and do you mind running Torco or additive octane booster regularly? It’ll keep you safe if you want max power on 93. If you can live with less, a few less degrees timing is perfect for safety.
    I prefer the lower pulleys but upper for simplicity, I’d say 2.4 with a BPS idler.
    VMP twin 69 TB or CJ mono TB.
    I’d discuss the CAI and SCT vs HPT with your tuner, but that will be more than fun on the street.
    Better have some sticky tires.

    I'll run 15k miles a year on it probably, so lots considering what most shelbys run. And yes, no access to any corn or anything higher than 93. Personally you couldn't pay me to run torco through my car. So either a mild 93 tune, or aggressive 91, whatever it needs to be run on the street, and on 93. Again, dont need or want to run this every day on 11, but up on 9 would be nice ;-)

    Twin 69 work on the stock bolt pattern? Or require an adapter?

    And your running everything from lund correct?

    The twin 69mm T/B bolts to the GT500 factory elbow, only the KB168, VMP160 or VMP173 need a adapter, but personally I would stay away from all those big mono blades. The twin 67 or 69 is the best option out there.

    agree with all above. I have cams and love them. Idle is cool made good power but fuel went down 6-7 mpg. Not smooth driving, always have to deal with a little bucking. At stop lights raw fuel smell. Again love the cams but lots of down sides. And the price tag for cams, springs, and install gets pricey

    Give me a shout and we can talk about your objectives.

    I don't sell parts so there is no pitch.

    If you need a tune, that I can do for you.

    Otherwise I assist you in planning a smart pathway.

    Agreed with the above that BJ will get you setup best for your goals if any and get you the best tune possible. If your looking for parts I do have a twin 65mm CJ throttle body for sale for $400 shipped as well as an unmarried X4 for $250 shipped. Also your ataks will sound ridiculous with any kind of O/R pipe, in fact my stingers were too much with an O/R H so I switched to tourings because stock was quiet enough so the tourings are near perfect IMO.

    Bj did my '13 mods & tune back in '14.
    The basic twin 67, 2.4 pulley & tune. On 91 octane makes 675 RWHP. I use torco when I'm playing harder.
    The car runs flawlessly and always has just like Bj said it would. I've got BMR suspension goodies & a tire that hooks 100%. I've walked several higher HP cars repeatedly because they can't stick the power they have.
    A guys doesn't need 900 horse in a street car to have fun!
    And, when not in boost, drives like a normal car.
    Contact Bj and you won't be sorry.

    Your path forward is pretty simple assuming you don't want to go the route of blower upgrades, etc.

    - 2.4" upper
    - VMP twin 69 TB
    - JLT 123mm or PMAS 120mm CAI
    - One step colder plugs (NGK TR7IX)
    - BAP (if necessary), you'll probably be fine without one on a 13

    I'd go with an Ngauge for your tuner. The ability to datalog by simply pressing a button and without hooking a laptop up is a huge plus. If you don't already run gauges then it'll also double as a nice why to monitor some PIDs when you're not logging. All these upgrades plus the long tubes and offroad X are really going to wake the car up.
