Message	Taking out the recirc's in exchange for the BOV means changing the way the map (off/on throttle) was design on our cars. On our Z's the computer (JWT, z1, etc.) compensated for the extra air being pushed into the intake by the recirc's with more fuel but when you deleted the recirc's for the BOV's your Z will run rich because the ecu does not know the recirc's have been taking out. A couple of example would be black smoke between shifts, and stalls between shifts. How is that explanation? Do you think it was simple explanation for the average Joe? I know you are going to reply. :-) BTW if you look at my profile I do have BOV's and my ECU compensates for it. www.SoCalZCrew.com **Dynoed at 371.2 rwhp. and 362.3 rwtrq. @ .9 bar on pumped 91 gas no time tweaking 3/11/03** **Dynoed at 411 rwhp. and 452 rwtq. @1.15 kg. on race gas 104 no time tweaking 3/28/03 **All numbers are SAE corrected**
