In regards to the car stumbling on its face with a blow off valve. You are correct...and incorrect...We are going to be using the Turbosmart blow off valve which is a two stage blow off valve. If you're simply driving around a parking lot then it will re-circ back through. When under hard driving it will blow off into atmosphere.
I might not be a tuner but I'm also not an idiot...I understand that by removing the metered air from the system that the car could potentially stumble and possibly die because you're taking the air away after it has already been metered...Don't need to be a tuner to understand that. I actually addressed this same question in the technical discussion thread.

Thanks for the response. Hmmm.. I guess I need to pose the same question to the guys at Uprev. I truly would like to know how tuning for a 'draw through' setup on an OEM N/A car with an aftermarket F/I kit is better than tuning for 'blow through'. I do understand the advantages of 'draw through', but the tuning is what concerns me. The IATs are certainly different (much hotter) than what the MAF is calculating for. This is a fact.
Truly, I wasn't implying that you are an idiot. That whole tone/inflection thing. But, even if you use a two stage BOV that recircs as lower pressures, you could still achieve a rich condition when it vents to the atmosphere. Again, any BOV in a 'draw through' setup is certainly a problem.
EDIT - I don't want my question of does this Vortech blower sound better than its predecessors to be lost in the dialogue re: MAFs. Can we hear that bad boy?
