I put on a couple cat pipes temporarily to have my LX e-checked.
Will lowering the FP and removing the supercharger belt help as well? Will this be necessary? If so what should i lower the FP to?
Thanks in advance. I wanna get this done tomorrow.
well actually 38-40psi with vacuum off is stock... i put some universal bolt on cats from autozone on my o\r h pipe, kept stock timing, an lowered f.p to about 30 with vacuum off an it passed with flying colors.... This was also with NO EMISSIONS EQUIPMENT!!! no egr valve, smog pump etc.... the tech was cool an told me as long as it passed at the pipe i was good!!! but yeah it didnt even register on some of the by-products... he thought i was running something funny, but just 87 octane... good luck!!!
