WHOOOOAAAA!
 

Just got the X back today and I can't get this silly grin off my face! WOW, its like I got a brand new engine! The car not only idles buttery smooth, there is no more hesitation pulling from a stop or while rolling. I swear it seems like I gained 50hp and 50ft lbs torque! Just amazing! Wow, so this is what a 4.8is really feels like. Ever since I bought the car, I felt that my 740i sport was a faster car than the 4.8is due to weight/gearing/etc. But now, OH MAN! The 4.8is is one fast SUV! I gotta take a clip of the x-pipe now! I should have done a before and after b/c you guys would be shocked at the difference in the BARK of the engine. It just sounds totally BEASTLY!

Nice to hear!!

Yes they are beastly! Did you have the intermediate levers and x-pipe done at the same time?

x-pipe I did 3 weeks ago. It sounded good, but when I parked the car, I just revved it up to hear that nice sound, I was pleasantly surprised!

so what gave it the better performance. computer upgrades at the dealership?

:thumbup::thumbup:

JT, who did your x-pipe? Mine is still sitting in the box. Did you bring it to a local guy? I need to do mine...

I used Z Performance in Corona off the 91/15 fwy. The owner is really cool. Labor was only $120 and it was a clean job. I used them previously for my dual magnaflow install on the 740i. They're cool and let you watch.

Now for some fun! :)

I got the intermediate levers replaced. Night and day. Had a bunch of other work done too while it was there and it is like a new car again.

Thanks.. I'll go there.
