Makes it sound like a 10 second truck anyway. :cool

Diablo
I had the same feelings about the tuner the first evening. But after a couple of hours the next day I could really tell the difference. The increase between shift points was very noticable when entering the interstate. I am not usually a heavy footed driver. I was doing 70 half way down the ramp. It seems to work best above 2500 rpm. I broke a tire loose in second gear and I have not done that in any stock vehicle with an automatic. I did say stock. Well, let me back up, my parents had a custom van in 84. If you put it in first and held the gas to the mat, it would shift on its own eventually. I think it would "chirp" a tire.

I just applied the Diablo tune and I'm a little disappointed as well. My 0-60 time did not change. I can feel quicker shifts and more response at speeds above 30mph, but what I wanted (faster 0-60) has not materialized. It looks like that my MPG may have dropped slightly as well (18.5 from 18.7).
I will leave the tune on for the next week just to see if it gets any better..... :yawn

Looking4anssr: The best 2 ways to improve 0 to 60 DRAMATICALLY are:
1. 4.56 gearing
2. Hi stall torque converter
The sS is so heavy that even after improving my 0 to 90 mph time by 3.7 seconds over stock, the 0 to 60 improvement would be small in comparison, as the engine struggles to get that 4960 lb (with driver and fuel aboard) to the decent part of the torque and power curves.
You need to let the engine rev higher quicker in 1st gear to make meaningfulimprovements. That's why the gearing and the hi-stall torque converter are so effective on the SSR.

That is true and this winter I am going to bullit proof the transmission and go with a smaller TC with a higher RPM but the funny thing is that is where I am getting most my power is 0-60 after the headers, Can't pull hard all way through 1/4 mile the way I would like, Still in the 13.60's, Off the line I can smoke the tires at will on blacktop, At the drag strip I break them lose about 12 to 15 feet, Wish you could see and hear this thing coming off the line, They are getting tired of seeing me, I won top dog as they call it when you out run everything there last week, I am runing low 1.9's 60 foot time with the tire spin, 1/8 mile I am flat out running the new GTO's and VettesJimGnitecki said:

Woohoo: Yes!
The lower the power to weight ratio, the more impact reducing weight has.
My computer software told me that when my 04 SSR was stock, simply having 14 gallons of fuel in the tank versus 2 gallons, and me versus the typical 160 lb test driver, would turn the 7.6 second 0 to 60 time claimed by GM into 8.0 seconds for me.
Now that my SSRE's power to weight ratio has improved a lot as a result of the mods that have been made, the impact is down to about 0.2 to 0.3 seconds.
When I made my cross country trip from Atlanta to Homecoming in Detroit and then home in Austin, I had all the gear in my SSR that I might need when going on contract assignment. That added about 300 lb. I REALLY noticed the difference after I got it out of the vehicle!
Your SSR never feels as good accelerating with a passenger in it as without.
To look at an extreme, this is why a supercharged Mini Cooper can stay with an 03 / 04 SSR in acceleration. The Mini weighs less than 60% what the SSR weighs.
Be careful in choosing your race oponents.

Jim,
Thanks for the info.
I did get one of my 0-60 runs down to 6.06. Where I put my left foot on the brake and released it at the same time I pressed the gas. (I have not yet pressed the gas and brake at the same time.) I have never had my tires spin on dry pavement and I noticed that even with the traction control off, if I jam the gas I will get a little chirp then a little slight stall and then I will take off. I figure that if I don't jam the gas I can get a better time....but I am thinking about restoring the factory tune because I don't like the new shifting, which at times can actually jerk my head back. Can't imagine that being good for the transmission.
I think that I will try their 87 octane tune just because it's there, but now I have the impression that I have to try something else....
