AMG 32 Renntech ECU and Pulley mods?
I have seen the increases in h.p torque and power , but what numbers are there on 0-60 and top speed with ECU and/or pulley change out with Renntech?
1. What average 0-60 mph decrease do you get?
2. What is the top speed obtained?
3. What disadvantages?
4. Is it really needed? Your own opinion please.
Thanks
