I for one have had success with the "little guy" tuners on previous cars. I think that everyone just needs to see the results that each are claiming and make a personal decision based on hard facts and desired outcome.

More money, less money, aggressive, conservative, reliability, power, are all personal choices.

I for one am looking forward to reading (..and hopefully see video) the results from both MHP & VRP before parting with 10k to Renntek or Barbus...

Here is the stage 2 RENNtech ECU dyno.

For anyone who is local to us in San Diego, we'll even offer free pre and post dyno runs for you over at the dyno shop.

Thanks James. Can you post the price so that we can remove speculation from the post...?

Interesting that the Renntech chart shows a baseline of ~350 hp when the "agreed to" average is 374 hp (see other threads).

James@ACG

$3495, local customers get same day service, non local customers will have a 3 day turn around.

How come you are not listed as one of Renntech's authorized dealers on their website?

MPH is doing ecu and tcu if ppl dont care about the money, y not buy a spear tcu and a spear ecu and you will have more power then both does tunes. and you would be able to swap the ecu and tcu when going to the dealer. yea its ganna cost a prety penny but i think its worth it. i rele dont care if something happens to my car, just swap the ecu and tcu and you will be fine and it wont cost you 10grand

I realize that some individuals show C63's with 375 HP, but we have done over 15 cars at our Lake Park headquarters and they have been between 342 and 355 HP at the wheels, our numbers are usually conservative. Our ECU V2 software is developing on these cars between 408 and 413 HP at the wheels.

What is important to us is the difference between the baseline and the final tune.

I personally have been doing RENNtech for the last 3 years, however I was given an opportunity I could not refuse to open up our own shop with a few partners. Both Ken Rudy and Bob Brady can verify that we have the proper equipment to flash your C63 and are authorized to both sell and install RENNtech products.

I'm sure if you sent them an email inquiring about RENNtech in the San Diego region, you will be sent to us.

James do you know if that was a 4th or 5th gear pull?

Thanks
