Was thinking about stacking with EFI because I like all the readings available from the Attitude monitor, boost, EGT, gear, etc. However, after a recent install of a boost controller, the Attitude boost was way off. If stacked with EFI, will the readings all be off like boost, air temp, engine temp (very imprtant since dash is way off), fuel temp, etc? And, I've already installed a nice mount for the Attitude, painted and all. EFI without Attitude would already require a EGT and new pillar mount. Dash trany temp is pretty close, so could live with just the GM trans guage.
