Much better than the the stock PSS. I am running a catless downpipe, MST intake, and tuned by Justin at Twisted Tuning on MHD. I spin in second but 3rd gear is a dead hook. I have been really happy with the Conti's.
I have 295/35's Conti ECS and they look good on the stock wheel even with the softer sidewall but keep in mind the 555r2 has a softer sidewall as well so they will "bulge" a little more than the PS4 or PSS.
Been running MHD for a while now. About 4 months on the OTS tunes and custom tuned for a few months now. Solid product and is very user friendly. The Wifi adapter is a must!
Awesome! Looking forward to the sound clips!
Echoing on what 2Cool said, I would definitely stay catted to avoid a CEL if you can't tune and to keep the exhaust note crisp
The feel good. I much prefer the rounded profile of the ECS compared to michelins and they definitely ride softer compared to the PSS in my opinion. I am tuned and finally have traction in 3rd now which is great!
I had an AFE catted downpipe and the smell was non existent. Currently running an AMS catless, tuned, and the smell is still bad. A tune won't fix that unfortunately.
I have the MX and it does not trigger the alarm either. The MHD wifi adapter does trigger it which I found odd but these cars are smart. Can't get much past them.
Reliability shouldn't be an issue.
I ran a downpipe, intake, & Titan Pro tune piggy back for a little less than a year with no issues. Now I am tuned by Justin from Twisted tuning on MHD with the same mods and again no issues. As long as you have a solid tune, you will be good to go. These cars...
Finally made the switch from the Titan piggy back to MHD OTS Stage 2. All I can say is what a difference going to MHD. I know Ecutek is all the buzz now, and rightly so, however MHD is ridiculously easy to use and flash so big kudos to them!
