    2009 Mustang GT keeps blowing fuse 47

    A few months ago we had some heavy rain where I live, and I may have driven through some large puddles and kinda drenched the throttle body. Since then, I've been facing an issue with the wrench and check engine lights coming on and the throttle response is almost non existent. After a little...

    2010 Mustang GT Tranny/Rear Diff noises

    Hey all, about 3-4 months ago I purchased a 2010 3v manual and the problems only but started. The rear diff started a nasty whistle, (I'm gonna call it the "kindergartener's musical recorder flute") only when I am using the gas pedal, and as I let off the second I let off it goes away and theres...

    Rebuilding a 2007 GT

    Hey guys, I am new to the group and have a couple questions. A buddy of mine has a 2007 GT Premium that we are currently in the process of “restoring” (it has had 10 previous owners who did not treat it so kindly). We are trying to return it to almost stock (with some tasteful OEM+ mods and any...

    4.6 3v Auto into 4.6 3v manual car

    Hello everyone, and thanks for taking the time to read. I recently purchased a project car (2005 Mustang GT) that needed the engine repaired, so I’m currently working on that. But the end goal in purchasing this car was to put that motor in mine (2006 Mustang GT) since it’s built and has a turbo...

    What are your general goals for your build? I’m trying to figure out mine and am looking for input.

    If I every decided to do major power upgrades on my car an 07 5 speed GT, I’d probably pick Brenspeed’s Paxton Novi 1200 pro charger kit that can push apparently around 500 rwhp if paired with cams ($850) , and after a remote tune, is this even actually possible? The kit and tuner is $4,800 I’d...

    3v turbo build wont pass emissions

    Hello everyone, I have a 3 valve with a turbo that I picked up for a pretty good price. I decided to jump into it knowing that it wouldn't pass emissions due to multiple monitors not completing. Most of which are the 02 monitors or a catalyst monitor. It does not have a cat and the only o2...

    Car still running 190⁰+ even with 170⁰ thermostat

    So I installed a 170⁰ thermostat and set the low and high speed fans at 186⁰ and 190⁰ as instructed a couple months back in my 2010 GT. I never actually checked with my handheld tuner the coolant numbers till now and even when cruising down the highway on a 70-75⁰ day the handheld tuner showed...

    09-10 cmcv removal

    Within a week I'm gonna be getting my 2010 GT properly tuned at a reputable local dyno shop. I'm thinking now is the time to remove the cmcv plates that are built into the 2009 and 2010 intakes. I also know that Steeda has discontinued the plug kit they made for these intakes. My plan is just to...

    Blow-by Talk and Fix

    I was under the hood today and saw at the connector tube between the intake and valve cover, it made me wonder how bad blow-by truly was. My mustang is at pretty high of mileage and I'm not sure if there's a point in putting in a catch can at 150k miles. How bad is blow-by on/for the 4.6 engine...

Been doing some work on the car here lately getting the tune dialed in had ran into a few issues along the way. During this process I've had the manifold off an when looking down...

    Shifting Problems

    Car info- mutha thumbr cams, cai, x pipe, mufflers, bama tuned, Ford Racing lowering springs. While driving the car normally shifts under 3-3500k it shifts smooth and as fast as you can change them. Then at the track or goofing off shifts above probably 4K it’s super stiff and asks like it’s...

    Cammed idle issue.

    Okay I have a 2010 Mustang Gt, xpipe, pypes mufflers, steeda cai, mutha thumbr cams, bama email tune. The car runs decent, not what I expected after the cams, I thought I would be able to feel some more power on the butt dyno. Besides that the bigger problem is while driving and changing gears...

    Cam issues

    I installed comp cams and phaser limiters and then uploaded the bama tune. I have a cai and x pipe/ axle back, now the car runs like complete crap, absolutely no power, runs rough and is jumpy at low speeds and can’t idle at one rpm. Is this the tune? Or do I need to take it to a real shop for a...
