Renntech

Hi,
I was wondering if anyone could give me insight on how noticeable of a difference in performance one would acheive by getting a ECU/TCU tune by renntech on a cl600tt?
Is it worth my 5k?

this post seems a bit peculiar seeing as there is a whole thread on the credibility of RENNTECH right now,

but I can tell you this....

give me 5k and I promise your car will be faster than any renntech mod you can do for the money....

I gained over 125 RWHP with the Renntech tune on my old CL600. The difference is HUGE! You are going from around 500 hp to over 625 hp. That's a big bump in power.

There are other companies that do a ECU/TCU tune for a much better price. You may want to do a little more research before spending the money.

Since they're all going to be pretty much the same, what's the cheapest tune available?
