Its not a linear remap of the MAP. I have SAFC monitoring its output signal. At idle it reduce air to lean out mixture (can't do that with my feet

) It then adjust air according to rate of change of throttle to lean or richen mixture.
Its a simple piggy back for people don't have lots of mods and don't want to spend time and money to tune a SAFC or stand alone ECU.
I first saw it in Turbo Mag with dyno proof of 9% gain. Haven't dyno mine. Test 1 sec better 0-60 with G-Tech Pro. No max HP gain with it. Engine has fast respond. It was tested on 92 Corolla 4dr.
Does it worth it? Don't know. Still need dyno to proof it works. My Corolla was fast. Then again Jet is a good company.
Jet got V-Force for 4 cyl and 6 cyl Toyota. Also got ECU reprogram. Go to
