DING! (sound of me chiming in!) LOL
I had discussed all the pros and cons with Inmotion (in Oregon) and told him I was coming up on business and could I drop off my ECU and have him tune it. He said that for insurance purposes, I could not drop it off and had to send it overnight.
I had my SRT6 dynoed locally before I sent it in and saw a peak of 291 pre-tune. After getting my ECU back from InMotion, I took the car to the same dyno under nearly identical weather conditions and the dyno showed a slight DECREASE. Granted it was now about 1% less, but less none the less.
This confirmed what my "butt-dyno" had indicated. Essentially there was no difference before and after. When I talked with InMotion (both phone and email) they said the same thing mentioned in the post from dinasrt "...I asked him what he thought of E.C. and said he wouldn't talk bad about another Co. to make a sale, but then immediately tells me if I wanted to go for the "smoke and mirrors" and "they probably don't have the proper equipment to really put the car in dynotune mode because that costs around $50k."
I called a number of tuners in SoCal who said they have tuned a number of AMG cars and NEVER used the special "computer" mentioned by InMotion.
At CAA in St Louis I decided to let EC tune my baby. I told them the story and they gave me a "no money paid" guarantee that if they could not improve the tune, they would set it back to the InMotion baseline and not charge me anything.
Bottom line, it was the best money ever spent. The "butt dyno" was puckerlicious. I could spin the tires from a stop with the transmission set to 2nd.
I did some testing with my Passport and pre-tune my best 0-60 time was 4.9 seconds, after driving back from CAA, I retested to a best 0-60 time of 4.4 seconds.
I wrote InMotion about all of this and asked them to reply, but got nothing.
I HIGHLY recommend EC and would not even consider anyone else!

Ok, just so everyone knows. Any tune purchased through us is always and will always be eligible for a FREE reflash. Canned/im persona/ dyno whatever the case may be. We have tuned over 400 srt/32 cars so we have a ton of canned and dyno tested and proven files for ANY combination of mods on the car. Thats why we ask for mods when sending the ecu or tuning on the spot. If someone just hands you a file without asking run swiftly. These cars are very tempermental and bad things can happen if not done correctly. This is also why we offer free reflashes, if you change a mod then you want to be running the best and safest version of the software for the platform.
The inmotion guys crack me up. We keep hearing a lot about stuff like that from our new customers that had been going with inmotion. SRT SIX karl can chime in with his story about how he was told that we couldn't "custom" tune. We put him on the dyno and showed how we modified settings throughout the curve as well as changed his tune to his driving style with shift points/torqe mgmt.
50k for equipment, LMAO I wish!!!. For the record, to date, we have invested in over $300k work of tuning equipment. This includes all of our dealer handhelds, our 2 master units, slave units for remote tuning, 2 optican desk units, as well as a few BDMs for doing the newer 63 series cars, 2 mercedes star units that are brand new, not to mention we just upgraded our Dyno to the newest and best unit on the market.
32krazy! is right, dynomode lol. Why in the world would we invest in equipment when you wouldnt need it.
Bottom line is no matter who you go with, tune that baby. The crossie is an amazing ride, and even more amazing with a little more pep!
