Please post here if you have something to add to the original question. Like I said my searching turned up nothing in comparisons. Just "my car feels stronger, it's so much smoother, it rocks, my butt dyno tells me it's a huge gain, etc". The normal stuff you hear when someone adds some performance mods. One person said it doesn't make much of a difference and another person said it drops almost a second off 0-60 times??????? If you have something to give this thread by all means. If anyone has any input or can direct me to threads that do cover this question please post here. I know this subject of chips as been covered a million times, but I found nothing of actual performance gains. I know a TCU chip is HIGHLY recommended, and a ECU chip does make a noticeable difference. I am not asking what chip to get....just what kind of performance gains to expect in real world numbers such as 0-60, 1/4 mile, etc. Thank you to the two people that actually answered the question.
On a positive note I have not heard of the viper tuning...I will make sure I look at it in the other thread.
