I have read this before, and I have hesitated on getting S2's for that reason since it is a DD.
I also read that tuning helps the vibration smooth out.

Can anyone confirm that?

thanks

LOL @ the guys complaining about vibration in their Evos.

You want comfort? Buy a Mercedes.

:lol:

My evo 8 has lower and upper hardpipes,turbo back exhaust its a borla and looks fairly stock not overly loud either,255 walbro pump and an intake I made 358 and 332 spiking 22psi

Tuning will smooth it out to an extent. Gsc s2 cams will have the aggressive idle if you want normal idle and more mid range power get the gsc s1

FYI u wont pass ca emission test with a tune and mods... u will have ur tuner to upload ur stock basemap back into ur computer to pass... just to let u know that there is ups and downs... either stay stock and pass or sacrifice and go for power...:beer::mitsu:

Passing smog on cams has been done before and yes you can pass with a tune.

Where are you getting your information from?

:confused:

The smart thing do to is to run https://www.evolutionm.net/forums/ec...hramod-v7.html and run a smog map that you switch to.



Not that I would do that or anything...

;)

Depends on how aggressive your cams are. But my buddy has HKS 272/272 on his stock head and with a great tune, it barely even sounds like he has them.

Another buddy is running HKS 264/272 and you can tell by a stranger idle, but it doesn't sound loud or anything.

I made 329/ 312 on crap cali 91 and 23 psi stock turbo, 100% stock motor and cams, stock o2 housing and injectors. My only mods are ETS 3.5'' FMIC, ETS 3'' intake, ETS LICP & UICP, ACT clutch and flywheel, walbro 255 fp, MBC, HKS carbon-ti, megan DP and test pipe. I'm adding a c.o.p, mona lisa manifold, and o2 housing because I'm trying to crack the 350-360 whp mark myself. Thats a pretty solid/standard list of parts for a stock turbo set up. The only thing I would change is the TBE because of the cops in CA. If I had to do it again I would go with the RRE stealth TBE
