Third Run with tune and 79mm pulley: 577.84 and 518.19 tq.
That's directly off the guys thread. He was on a dyno jet and tunes were from vmp
The other forum I'm part of all the 11+ guys who have roush are getting roughly 460whp. Tunes alone from jdm and vmp have shown 75-100whp increase. I can find the threads if you would like.
Stock motor or forced? I have a supercharger and I have to change them out every 30,000. If you don't have forced induction then I believe the service calls out for every 90,000
Oh yeah I think auto light ht1 are recomended for your car also. Could be Wong
Call me an idiot but is this a tvs system? As of right now I'd including everyone else would recomended getting it to a dyno ASAP! I know roush tunes run rich, but shouldnt be like you lost power.
