Will 30 tooth increase top speed??? MCN measured stock top speed at 90 mph.

I wouldn't expect it to increase top speed, I will however say their 90 mph is easy with mine. I was on the freeway catching some V-Tune runs and had mine up to 90 mph with plenty of throttle to twist.

 

Haha, was doing the same exact thing this weekend. Like M3's, it hit 90 mph very easily. If not for the VTune runs, not sure I'll be at that speed or higher very often.

 

Good thing the long arm of the law wasn't around.

 

Well the dealer is ordering the 30T an will install when it arrives. Is there anything I should make sure the dealer does?

I have a PC V Auto, will I need to call jamie an have him send me another Flash?

I know I will lose 6th gear light, but I thought someone has come up with a soultion to this?

Also will the speedo need to be adjusted, I read somewhere that it had to be, and a mathictic forumla was used a long with a GPS, I have the GPS?

Thanks

Robert, you don't need another flash for your PC V. You will not lose your 6th gear light. The speedo will read 5mph faster. I use my GPS if I want accurate speed readings. You can recalibrate your speedo if you know someone with a TTS. I think the re-cal code is 2345(?)

 

You will not lose the 6th gear light, 55 is now 60 so just do the math!
The procedure for the pulley change calls for certain seals to be replaced and certain bolts replaced with new one's. Should not have to tell a dealer to do that, some indy's may reuse those bolts. I would not cry over it if they reused them!

Thanks for your reply. I'll let you know how it works out.

Yeah, I just looked at my old receipt and wondered why 150 bucks for the extra parts(?) I didn't quibble about it - better safe than sorry!

 

TTS marries it self to the 1st vehicle it maps and will not work on any others.
