one of my supra friends has one on his car and he swears by it, but from what it looks like it appears to still be a maf interceptor and still mucks with the maf signal.hell for the price of the phr map ecu go buy an emanage ultimate and have all the features and more.DrifterTom wrote:i have a phr map-ecu. it is awesome, the only problem is you better have a great tuner and dyno. this is because phr doesn't have a map for the rb's yet. this equals lots of dyno time.
