OK, I hate to "highjack " my own thread, but living2be asked about the Predator and Miss Daisy.
First of all, I got to drive JimGnitecki's SSR with his brand new 4:56 gears and remapping of his ECU and I must say, this is how I expected an SSR to run. - QUICKLY! It has true, seat of the pants acceleration and is a blast to drive.
Well, after that, I just HAD to do something to Miss Daisy, so I bought the Predator from him, installed the Performance Tune option with it and lo and behold, even Miss Daisy now roars instead of a little bark.
Here is what Jim and I found after the Predator package was installed (about 10 minutes of work!):
1) Wide open throttle (WOT) shifts raised to 5,800 RPM (Lot more sound out the pipes, yeah!)
2) Shifts were made later (to use the max torque curve to my advantage)
3) Shifts were firmer (I loved this almost as much as the sound)
4) Timing was advanced (More low-end throttle response)
5) Cooling fans come on at 193 degrees instead of 235 (One of my main concerns)
6) Ability to modify any of their (Predator's) pre-set Performace settings. (I changed the 1st to 2nd shift from 36 MPH to 39 MPH and I may plan to mess with shift pressures for a little stiffer shifts. BUT, if I don't like what I did, I can reset it back to the Predator's default Performace settings, or even back to GM's stock settings when it goes back to the dealer for work. Both resets take about one minute! Honestly!)
Best performace money so far! Now that I've seen the results, I would do it again in a minute!
(Now, do you think my wife would like 4:56 gears for her anniversary present?)
