Props to nmp0098! Incredible tuning!
He is very very knowledgable about the LS4 engine and how it works. To be honest, some of the things he was telling me was foreign but he was absolutely sure of himself. We did multiple tuning runs and he perfected the tune. We did quite a bit to the car, however I'm sure he could point out the specifics better then I could.
Here is a thread he posted about tuning: https://ls1tech.com/forums/ls4-perfo...formation.html
After the tune my car was drastically different. The car shifts at all the right times , with even firmer shifts. DOD is off and my ears are loving it! I could just go on and on however you would think im sponsoring him!
I would recommend his tuning to anyone in the Michigan area. He was about a 3 hours drive from me, however it was definitely worth it.
DOD is completely turned off. In my case, I drive mostly in the city, so it is useless to me. The overall drivability and throttle response seemed much better with it turned off.
