That's a crock and you know it Joe. You were one of the main people that said that the engine would be "blind" to the SIR below its target hp. Sounds like you bought into Raetch's line of crap pretty hard. You picked the wrong horse.

Jake,

Sigh is right!

Only way that a motor will be blind to an SIR is if it is way in front of the air flow meter. This puts it outside the allowance for intake air in IT. Some will tune without the signal from the AFM and get right back to their original numbers. Just because "the tests" did not show this does not mean it can't be done. You way underestimate some tuners. Same responses I remember from the flat plate debate--got bit on that didn't we?? Wait and see the creative intake hoses that were opened up to the throttle body before you make your decision.
