- mercedes e 320 cdi avantgarde
Well after alot of research and speaking to different people regarding the best tuning option of the s 320 cdi i've finally took the plunge and ordered an gcl st3 tuning unit today.Spoke to gary who was very helpful and explained to me how the unit works and i felt reassured that this is a good product,gary told me that within the new software the gearbox is also catered for so as not to overload it with to much torque.Im going for a performance map and economy map as well as the unit holds three maps in total one being the origional in case of wanting to return to standard,although i dont think i will be doing ha,ha.Anyway i should get the unit by friday so as soon as the software is loaded to the car and i get the chance to try it out i'll let you all know what i think.
