I have been considering a ecu upgrade. I am considering either GIAC or FVD. Can someone tell me if they have used either and the results. Also considering a fabspeed exhaust. That is all I would do to car. Is it worth it. Also my boost is .7 bar. is that what other x50 owners are getting stock. What does ecu upgrade do to boost? thanks

 

JWGT2 has a used Fabspeed Moderate (1000 miles) from his old GT2 if you're interested?

 

I have a stock '03 X50 and will pull boosts of .8 and spikes of .9 in 5th gear typically. I listened to a few different exhausts this weekend and favor the Fabspeed

 

I just had the Remus installed and love it. Not too loud, but louder than stock when you want it to be.

The GIAC flash allows you to go back to stock at the push of a button. Can't beat that.

Fabspeed...all the way!

 

EP2 quiet on my tip. I was playing with a c6 z06 and went by him on a straight and he actually commented on the sound jof my e xhaust. His car screams when tacked up but I could only hear mine while we were both hittting it. Nice smooth idle slight burbling when letting off at higher rpms but sounds off quite nicely when WOT. Happy with it.

 

I have the IA stage 4 upgrade which included air filter, fabspeed exhaust, headers DV's and ECU reflash and hand held switcher and i have to say its been bulletproof so far.
Worth every penny.

How much for the used Fabspeed? Brad B

 

Are IA stage 4 and EVOMS stage 4 are the same?
