Remapping seems a much better solution that using things like EIFEs to trick the computer into going leaner. I have a Toyota Avalon and would like to be able to tune it. Is the learning curve rather steep? I wonder what I need in terms of hardware and knowledge.
You mentioned CROME as a software, chips, and chip burners.
Have you gotten any results?
Will take a look at this thread again. Need to go to bed
