Good day fellow members!
I am opening this thread because the time to ECU tune my C6 RS6 has come, so I would like to ask to those forum members that have, have had or happen to know what is the most reliable ECU tune based on your experince for this car.
I live in Mexico and the only tuning companies here are Unitronic with a 660hp tune, Revo with a 700hp tune, APR with a 665hp tune and some lesser tuners.
So, after having bad experiences with my C5 RS6 using Unitronic and Revo, my only local option would be APR, but as far as I know, since APR is an USA company, they do not have the disponibility of "experimenting with C6 RS6's in order to make a powerful and reliable tune, and also the price for the tune is, in my opinion, very expensive... I got a 4,500.00 USD quote just for stage 1.
So I am asking fellow members from all parts of the world where the C6 RS6 was sold what tunes have you had and what has been the experience with that tune on your car? I have seen 700hp MTM C6's @ Dragtimes info keep up with a Lamborghini Murcielago LP 670 SV, GT-R's, etc, but I have also read (I do not remember where) that the RS6 C6 Viper 700hp tune and 700hp MRC tune were pretty good and reliable (both @ arround 1,500.00 pounds). MTM 700hp tune is @ 3,700 CAD.
Any info will be appreciated as I am willing to ship the ECU wherever necessary in order to have the "best" tune for this car.
As a note of information, here in Mexico we get up to 40°C in the summer and we do not have high octane gas, the best pump gas is a 92 Octane one.
Thank you in advance for your help!
