I just registered but have been reading this forum for quite some time. I just got my 575 roush blower installed with the roush calibration. I'm not a fan of the roush tune,...throttle response is garbage. I haven't found a place here in the Phoenix area that has the software for the 5.0s to get a dyno tune so I may go with vmp or been speed calibration. Don't know yet. I noticed I have a ticking sound very noticeable coming from the drivers side when accelerating only. Idle and revving it sounds fine but when driving and accelerating it starts ticking. Any ideas what could be the issue? Oh and I'm no expert but why are my dyno lines so squibbley(lol nice word choice)?

First off, that's an awesome blower! Can't wait to get one... Someday lol.

Ticking on the drivers side only while driving? Does it seem to be coming from the motor or possibly suspension/brakes? Did it start after the blower was installed or before?

Lund, vmp, and evolution (although I'm pretty sure kind does evolutions tuning) I would look at for possibly remote tuning your vehicle.

Also try to post a vid of the sound

It was after the install. I wish I could say exactly where it was coming from,...seems too far left to be the motor. It seems like its right where my feet are at. I'll try a video clip in the morning.

Could be something they installed is rubbing, or something wasn't tightened or something?

It's probably that your car is too bad *** and the world starts falling apart when you drive it. IMO

I couldn't stop laughing!!!

If I had known the roush calibration had such bad throttle response I would have installed it myself but I was thinking warranty. So I just threw away $900 for an install. I plan on taking it to them tomorrow and see what they can do.

So are you happy with it overall?? Im about to buy the Paxton kit for mine but keep thinking it will haunt me if I don't get the roush. Ive been trying to decide for 2 weeks now. Different opinions and advice keep flipping me back and forth. I wish I could try both and then choose!

To me that dyno graph looks terrible. Not the numbers but the line. It shouldn't be up and down like that. But may be something going on with the dyno.

I agree... It looks like the a/f ratio is constantly readjusting on the fly causing the ripple effect there... Something seems off with that. If there's bad throttle response that's probably a different issue but also a bummer.

If I was you I would send those dyno graphs to a reputable shop that has tons of experience tuning the new 5.0 and also tuning the new 5.0 with roush blower. Like brenspeed or maybe see what roush could tell you. Cause that power line and curve should be pretty smooth, that doesn't look right at all.

Re: 575hp roush blower

MANY have issues with the OEM Roush tune (it kind of sucks as you know) A real tune by a REAL shop will be better of course.

Ya I've been in contact with brenspeed and they follow up within minutes. I'm gonna get a tune from them and a few others and drive each for a week or two and dyno each as well to see who I like best.

Re: 575hp roush blower

You might want to pick one company and stick with them, SC tunes run around 175-300 bucks and that could get expensive..

I hear ya man. Here in Phoenix I've only been able to find one shop(so far) that has software for the new 5.0. I prefer Marty at extreme performance in Goodyear, az but he doesn't have it either. Xtreme Motorsports can do it, they use diablo port tuners. Don't know if they're good or not. Brenspeed said they're releasing a calibration for the 575 kit mid next week so vmp or brenspeed is what I'm looking at.

U dont think the throttle response could be causing the shaky lines? Take it to another dyno to tune it..

No. That's just the tune. It's like that bc the roush tune is very conservative, it's cutting power basically through out the power band when it wants to make more. Need a better tune to free up them ponys!

Any ideas on why I get a soft ticking sound only during acceleration? Not at idle revving, just when accelerating. Waiting to hear back from the installer who is waiting on roush.

Is it from the motor for sure? I can't answer for sure bc I haven't seen or heard a noise except for a badass sound when in a mustang with FI!

Here is a crappy clip of it on an iphone. Turn your speakers up or have the phone mic close to your ear. It seems like it doesn't make the sound in 1st gear but 2-6 only when i push the accelerator at any speed. Hammering the pedal and just lightly accelerating this ticking sound is heard. It's NOT heard when cruising, at idle, at idle revving. any ideas?

Man that's weird. Sounds like a old car with a exhaust manifold leak. I'd check everything and make sure everything is tight and sealed up good.

Congrats I'm Going to put that same kit on my wife's car. The dyno chart looks like the gap of the plugs may be to big. I have seen the same thing on fi cars when the plugs are not gapped correctly and it is blowing out the spark. I may be wrong but that's where I would start. It's free and easy to check.

Does kinda sound like lag on the motor, does it only happen at certain rpms?

It happens throughout the rpm band whenever I push the accelerator. It doesn't seem to happen in first gear but 2-6 its there. I'm gonna have it on a lift thus evening and hopefully I'll figure it out.

It could be something from the CAI. When you I stall one it magnifies all the sounds coming from the motor. Better safe than sorry though, probably should get it checked out

I'd get it checked out ASAP. Def not good with that much at stake. Hopefully it's something stupid! If you got it installed some where I'd take it back and tell them what's going on and it started when you left there basically.

So after some investigating I finally figured out where the sound is coming from. I was able to feel it in my left foot at idle when I revved it up around 4k rpm. It's the fuel pump(if that's where it's located drivers side Low against the corner of the engine bay). I gap checked all spark plugs and a few were a little off but nothing that would cause any issues. Had an exhaust leak just after the x crossover but it was very small.

Would the tune make the pump a little louder? Or is it just working harder for the extra fuel needed? I'll be taking it back to the shop and see what they can do sometime this week.

Very well could make it louder, it is pushing much more fuel to accommodate boost

Haha well I was in the right area just a ft away. When they installed the blower they were planning in installing the boost gauge but it didn't come in on time. The plug for the sound tube delete was removed for this and he forgot to put it back in so the injector sounds were being amplified through the whole into the cabin. Put the plug in and can't hear the injectors anymore. Glad it was indeed something stupid. Waste of a thread, I apologize.
