Don't see any or many threads on the renntech tune. Anyone have it and can post feedback?

Saw this a while back.

I don't and therefore maybe shouldn't comment...

but the tunes from all the major vendors are almost identical in terms of performance and smooth driving characteristics. Go with whoever is convenient/who you want to give money to.

Hey man. I know off topic. Can your share that sub/audison picture behind pass seat ??

kumizi

It's all hidden in the stock location so not much to see. I can't seem to fin the pics from when they were doing the install. I went with a shallow mount 10" JL sub so there's a ton of room back there to fit amp/sound processor/etc.

From my experience in the Porsche tuner world, there are differences with tuners. For example, Cobb offers an accessport where you can swap files in the comfort of your home/ garage while Giac has to be brought to a Giac dealer.

I am looking for something similar, plus reliability.

I'm coming from a Porsche too. I had an Accessport on my GT3.

On the Benzes, they all remove the ECU and flash it using the same process. They all offer the same 2 year warranty. They all produce the same hp/tq numbers.

Cobb is not prevalent in the Benz world but there was an AP style tune only on the dme for the c63 I believe- it was an OBD2 tune and had no dme/ecu removal. And while the majority of the tunes for the M157 and other engines are shelf in nature, one can dyno tune their car and get the max out of it; if they are local to their tuner and a shop. What I love about the turbo engines in the Benz arena is the gains in hp and tq from the simple ecu tune along with cheap pricing for such gains. The dollar spent for the hp/tq gained is a great "bang for the buck".


As for the GTS- I have the Weistec tune (have posted a thread here) and love it... great linear power along with throttle response. I don't experience with RT but Im sure their tune is solid for the M178.
