Installed ESS software last week on my E60 and after the Vegas Run I put around 700-miles on my car and it’s finally came alive.
I currently have the following engine mods on my car: ESS Software, Evosport Pully, AA full exhaust Secondary Cat and resonator deleted, RPI intake and BMC Filters.
Every engine Mod gives you a little more performance but honestly to me I really didn’t feel any significant difference until I installed the ESS software. ESS has enhanced all my modification on my car and they are working to the maxim potential finally!
Throttle response is significantly increased but that’s with most software upgrades increasing drivability. However the bottom end torque now is unbelievable feels like I just added another 50pounds of torque. Every gear pulls harder than ever feels like a totally different Machine. The car redlining at a higher RPM is also good now since I sometimes missed the shift point and hit the governor.
Even my GF noticed the performance difference in the car driving back from Vegas since I was exhausted I woke up to her racing another M5. I told her to pull up next to him and race head to head we started around 80mph and by 130mph she was 6 car lengths ahead unbelievable!
I was going to install headers this week, but now I’m reconsidering since my car is running like a champ don’t want to ruin the chemistry!!
For anybody thinking of upgrading the software ESS is my pick all the way!!
