Drove it around the neighbor hood today,tune is in bad shape lean in one spot rich in another.wondering if i need to put a one way valve in the map line,what little i drove it it seems to pull hard at part throttle and is bound to be a blast tuned and wot with some boost
my experience with a speed density mustang and a blower is that as soon as the map sees positive pressure the computer just shuts off till it sees vac. again. we used a one way check valve (the one for the cruse controle on a fox mustang works really well). the problem with that is that it would trap the vac. on the map side. so we drilled a really small hole in the map side of the check valve so it could bleed off the vac and that worked really well.
