Egad...this thread is still active. Stymee must be proud. I haven't been on here for ages since I sold my Mustang over 2 years ago. However, I am now looking for another one....maybe a '20 or '21 model. We have moved and there are no dragstrips close by so I want a 6 speed manual this...

Wrench code. It popped on just as I completed a quarter mile run. The car was still pulling, though. I forget what the code was but it was for low fuel pressure. Never a problem or CEL after installing the DW400 pump.

Yeah, stalling is NOT normal at all.

There seems to be some variation among different years with the Roush tune. My 2018 had perfect drivability. Other than a bit softer initial throttle tip-in, it was just like stock....smooth idle, never stalling, smooth shifts, etc.

I think there is a place for the installing tech to sign. I had him sign it and I mailed it myself.

I got my catch can, SC kit and fuel pump from Beefcake.

Lol...I have no idea.

This was my dyno:

You just described the Roush....and the woman of my dreams.

Oh, one more thing and this is a bit of a controversial topic: When I was considering superchargers, virtually all of the installers in my area warned me to upgrade oil pump gears and crank sprocket if I went with Whipple due to the higher redline and shift points. With the Roush, no one...

Oh yeah, I saw that thread. If powertrain warranty is a priority, Roush is the choice. For street use, the performance is stellar....excellent drivability and brutal acceleration....with sticky tires. There is lots of talk about heat soak with the Roush. I never experienced that here in...

Afternoon off? You must be a fast reader. I would need a week. What are your goals? Fast street car? Drag racing? Is a powertrain warranty a consideration? What is the climate like in your location?

I am surprised to hear that. With the Roush tune, the stock fuel pump was marginal according to many sources. I put a DW400 on mine to avoid a CEL for a lean condition. Stymee put a BAP on his. Wengerd has a great reputation so he must know what he is doing. Maybe his tune doesn't...

I have an M550i. Completely stock, I ran 11.6 @ 123. It is quiet, comfortable, and has lots of technology. It is an awesome combination of luxury and performance.

I never had any issues in Minnesota, either.

Good move. Based on your goals, the Roush kit was never going to be satisfactory.....especially in Florida.

Are you serious? Tell us more!

With the Mustang, I would drive to the strip 110 miles away carrying 2 drag radials, a jack, a cordless impact and an air compressor in the trunk with the seats folded down. Changing tires at the track and then changing back to street tires became a pain in the ass. With AWD, I just drive...

Yes, I replaced two vehicles with one. I had a Lincoln Continental and the Mustang. I now have a BMW M550. I recently ran it at the strip....11.6 @ 123 completely stock.

Last summer I contacted 3 dealers about ordering a GT500. All took my name and agreed to call me when they had allocation. None of them ever called. I ended up going in an entirely different direction. It is probably for the best from a financial perspective but I still wonder what...
