Hi Tony,
Mine is 2009 wrx with Ultrez
TBE. I read that u tuned your car from evolution R. I am also thinking abt retuning mine. Mine is just stock with the
TBE. So was wondering what is your car and model. How much power gain did u get from compared to a stock. What the evolution R is much cheaper than Ecutek which quoted me nearly $1700 for a retune and Verso which is approx $1200. Besides, the evolution R told me that i need to get a CAI before the tune. Is it necessary to get a CAI before tune?
Please give me a reply as i am entirely a newbie to the dyno tuning section. Your help will be really appreciated
