+1 I am not the one who will push not doing it yourself, because I do my own as well. Having said that, doing your own tunning requires knowledge about the car and being able to spot what its doing at any particular time. If you are going to be doing mods slowly as you go and don't plan on huge power levels, then doing some of your own tunning is fine. You will need a good datalogger, a good Wideband setup and a laptop for the Pro Racer Package. As for can tunes that come with the tuners, as custom tune for your exact mods and car is always better than the one that comes in it.
ive heard good things about dyno tunes, but also have heard handhelds get the job done too, just that dyno tunes are typicaly better. im not sure of exact reasons. im sure someone will post it in here!
yea thats what I was thinking. I have major mods and major problems with the ECU. I need a serious tune so I am prob going to get it dynoed. Should I pay someone $500 to flash it or $850 and I get the Xcal2. Also do dyno tunes correct daily driving issues like high drive idle and such? Thanks
