Today we are officially releasing the long awaited sequel to our EVT-610 tuning system for the 997TT. As some of you may know, our EVT-610 (610+ HP) tuning system has sent the benchmark for 997TT “bolt on” tuning systems for the 997TT. Our 997TT has already set the record for the first 997TT to run into the 10 second territory in the ¼ mile. With over 6000 test miles on the odometer, we feel it is safe to release our newest tuning system, the EVT-690R.<O =""></O>

The EVT-690R utilizes all of our upgrade components from the EVT-610 which are vital upgrades that reduce engine restrictions as well as reduce heat. Additionally, the software has been upgraded with the new GIAC chip switching technology with a very potent race gas mode. The powerful combination of the more aggressive GIAC software calibration and our proven formula of properly designed hardware components make this upgrade the most powerful bolt on tuning system for the 997TT, bar none.

This EVT-690R tuning system is currently available through Evolution Motorsports (AZ), Imagine Auto (KS) and Sharkwerks (Nor. Cal). It will be available for installation throughout our exclusive dealer network in the next 5-7 days.

What is the difference between your 610 and 690 kit? There isn't anything on the website yet.

 

We have not yest edited our website with all of the details. We will be adding more information to the site in the next few days. I will be adding more information to this thread shortly. Here are some photos of the dyno testing we have been doing.

 

Oh No! This is going to be very tempting since my car is at IV now...

Cant wait to see the goods and dyno.

Alex where are you? Oh thats right you are sleeping in...

 

mike hey whats the 690 kit dyno to the floor ...super interested ...ill call you in a little...

 

Well the good news N2it, is that you are at least 2-3rd's of the way there! More power comin' right up....

 

Keep up the great work Todd , Mike and the crew!

Alex, as I'm getting the straights installed next week might as well get me to the 690Stage ;-)

 

That facial grin is appearing again! Let's do it...

 

Sounds like Sub-3 seconds 0-60 might be possible. Unreal.

Can't wait for the dyno charts and, more importantly, the Driftbox data.

 

Can't wait to see the full specs and dyno, sub 3's would be awesome

 

Roger that... you're the same.. like 2/3rd's there!
