Who would be the best ECU tune?
http://www.singhautosport.com/index2.html
My take on ECU mods is this:
Brabus/Renntech/other expensive tuners programs are not better than the low cost ones done by folks like Singh since they are all controlling same variables and the code has been cracked on those, it's not rocket science. Now, someone can really screw up your car with the wrong program, that's certainly a possibility.
Does anyone have any definite information on what variables are the ECU programs modify, what are the differences between tuners, etc?
I make 525 RWHP and 595 Ft lbs of TQ to the rear wheels and still have bone stock Exhaust.. Car drives great and my air fule ratio is in very safe operating range.. Very safe!
