Those particular people, are not getting around SCT's limitations in order to deliver power. They are using pass through devices and hex editing the tables SCT does not make available due to incapabilities of reading the complete ECU profile. This in return, returns a more complete calibration file to the end user.
You and I have discussed this before.
IMO, this is the best post in this thread. Let's be real, all these guys can tune. The one with the most information and access of the ecu however, will be the one with the advantage. However, I feel like Mike has a point. When you start getting flown out around the country to tune big hp, sponsored, money cars. I feel like the care/desire to tune the basic cars gets put off to the side especially when you are dealing with people that probably have no clue what they are doing or how to even log and try to understand what is going on. With that said, I tried two so far, BAMA and LUND.
IMO BAMA's customer service is extremely slow and your experience vastly depends on who you talk to cause there have been times where I hung up the phone scratching my head wondering if the person on the other line even knew understood what we just talked about. Currently I am waiting on a revision from them as the car was not running as good as it can.
LUND, whoever this KenB guy is, his response time, even during off hours is unmatched. He changes what is asked and answers questions. Tune runs good, but could still use some touch up work. I'm not here to bash one or the other so take it for what it's worth.
IMO the big limitation here is what the end user could see about thier car. The sct device is sketchy at best imo. Some values log, some don't, some are mislabled and represent something else ect ect. At this point I am pretty much in Lunds/Ken's faith as the logs I do don't show much.
We need the ability to log each cylinder correctly to see how the ecu reacts, that imo is the next step. Now do the guys not using the SCT have the ability to do this? I sure as hell hope so. But I would like to be able to see it for myself. The price for these things is fair, pick a big name and go through the process untill you are satisfied or go onto the next one.
