By in front of he MAF sensor you mean between the filter and the MAF. Won't the nitrous going through the MAF screw up the little resistors? I'm curious as to how you guys are making your custom kits. Some pics? Diagrams? Where do "ya'll" hide your soleniods?

Has tech at a dragstrip every not seen your hidden setup? That would be the ideal situation IMO. Hehehe

 

Tech has never looked or asked me. Yes the N2O has to pass through the MAF. Thats how the computer adds the extra fuel. BTW, my bottle in my truck sits right behind my seat so i can reach back and turn it on.
