This product has been developed for MR2s using the 2GRFE engine, and that are experiencing a late opening of the ACIS Valve causing significant power loss in the midrange. On engines with the #3 intake manifold and using the Frankenstein Motorworks ECU, we have seen as much as a 25HP gain from approximately 4100RPM until redline. The dyno graph below shows run #5 as a before run that was done about a year previously and conditions were a little better than when run #12 with the ACIS Mod was done. This Mod will only help if your engine is showing the same jump in power around 6500 RPM. If you have a dyno of your engine and you see the tell-tale jump in power you NEED this part.
