Anybody come up with a solution for the diff whine after installing the new bushings? Its starting to bother me. Even contimplating trying to get the stock bushing reinstalled.

What injectors, fuel, intake, and tires were you running?

I don't have any supercharger at the moment, but may be able to get a good deal on a ford racing one. Just don't want the 627hp tune if that is all that is available.

So from high 11's to 10's with just a tune?

Want to know how they compare (if they are better) to mpss.

Now get her to the strip. Iwant to see what she runs:headbang:

Definately an alternative im considering.

Ok so it wasnt just roush that upped the power?

Is the Ford racing supercharger calibration the same as the roush. So 670hp instead of 627? I cant seem to find an answer.

Assuming you got yours installed. Is it working out better for you than with the torsen?

I believe the pumpkin referenced is not torsen. Just something to keep in mind.

Whipple is on my list but im also interested in other alternatives. 1/4 mile times with Whipple kits seem off which is partly why im not sold. Id like the car to run 10's on a good street tire. I dont care about power figures as long as it gets me into the 10s.

We go every year too, but not going to return a supercharged car to stock every year to pass obdii. Clearly im not as sure as you are. Love to know if you do pass. What kit do you have?

So was that car subject to obdii testing and did it pass with your tune?

I figured the tire would be a problem but roush550 did it with all seasons and a roush phase 1. However, havent seen anyone else do that.

Im kinda shocked that there are no responses from people who have tuner kits. Guessing there has to be a lot of them on this forum. Maybe they are scared to post or something ;)

So do you have a tuner kit that has passed emissions testing.

Reviving this thread. So has anyone with tuner kits passed emissions. Im talking a set like lund tune, id 1000 injectors, intake, bap, different pulley, etc. None of the previous post said yes or no. Thanks

Would a whipple stage 2 put me in the 10's with the following 1. 285/19 street tires 2. Catback exhaust only 3. 93 octane 4. 3.75 pulley 5. All the stuff in my sig. Thanks:thumbsup:

Few questions... So 3.8 pulley, no BAP, and the 47lb injectors that come with the kit, and stock exhaust? Does the 5400 you spent include the Lund tune? When you say base kit, is the complete kit that includes everything? Thanks. All really helpful info!
