wildebill308 Report post Posted May 18, 2016 I haven't had a chance to look at it. I would do nothing till I had a good Boost and EGT gage. I highly recommend them because of the useful information they make available. Bill Share this post Link to post Share on other sites

DD look into a software program that you can load into your apple unit that acts like a translator, for program language. There are some ,but I,m not up to speed regarding the software language Power Spec uses and the required Microsoft drive. Rich. Share this post Link to post Share on other sites

robertgable Report post Posted June 16, 2016 Power spec software won't do horsepower re-rate, but it can customize a number of paramaters. You also need a inline or nexiq adapter to hook from the ecm to your laptop. Share this post Link to post Share on other sites
