Yeah, below 6-7 psi, an intercooler doesn't net much improvement overall. Since you have to route back across the engine anyway, the intercooler is probably not much more work to install.

The ECU tries really hard to get back to the factory fuel map, so the trims keep getting adjusted. If you have a nice snug belt on a Blitz S/C, you can actually get the MAF to go out of range and throw a CEL. I've also seen too lean, too rich, and misfires across all 4 cylinders, but it's gotten better since I isolated a lot of the vacuum leaks.

Well I would think if the piggy back is doing its job efficiently it will keep the maf in check and I dont have a cel at this moment. Did when i was done with install but no codes now.

The Blitz piggyback is really simple--it just forces the ECU into open loop when the magnetic clutch engages. The MAF signal doesn't get intercepted. Perhaps the piggyback for the Rotrex can be setup to clamp the MAF voltage, or just use MAP instead?

Hi OP,

Any updates on this Rotrex setup? Can you give any reviews on this product?
