    Debating to get a JC chip for the eta

    Im looking into replacing my dinan chip with a JC chip, but i have no idea if its even worth the extra $200 and not feel a difference. i read reviews for almost a whole day and people are praising this chip saying it made a difference

    has anyone have experience with this chip?

          Dinan makes very mild chips from all the Internet hearsay and experience.
          Your best "wake up" mod for the ETA is a shorter differential.
          The 2.93 is a couch potato.

            is the 3.25 overkill or is it the sweet spot of the eta?

              I believe that's the sweet spot, but don't remember what I've read over the years.
              3.73 is the highest you'd EVER want to go on an eta and that's over kill still IMO.

                don't go with 3.73, you'll hate it. my eta with 3.25 on the highway drive my crazy at times. i have a mark D chip and 3.25 lsd on my eta, run 16.7 1/4 mile with bad mismatch tires and bad launch.

                  3.25 differential is awesome in the Eta. Definitely go with the JC chip, Dinan chips... suck.

                    I second the 3.25. If you can only find a 3.46 it won't be absolutely terrible (as long as you don't do a lot of highway driving).

                      I'm still on my open diff.

                      but get the JC chip. You will love it. It's actually kinda funny, my cars stock as can be, except for the chip, and they're like "whoa, this is a 2.7l six? from EIGHTY FOUR?"

                      Worth every penny.

                      took me like three seconds to copy/paste it- FOR SCIENCE!!

                        its just the torque that people are surprised about. its no faster then a single cam civic.
