Run your egr through a Small intercooler In front of the radiator. Egr cold air induction! I will continue to run one if i can once its working properly. Really does no harm other than cluttering the engine compartment with 2 more hoses...high lift cams need not apply as their low vacuum may fool egr activation. I noticed my little truck ran about 20 degrees hotter without egr hooked up or plugged. I always thought pcv introduced under the carb was ludicrous too. I think some modern cars dont have egr as they use MAF meterz that cant read egrdilution as it doesnt pass through the meter? I know thats an issue on turbo cars when the blow off valve opens, the motor controller is like " what happened to all that metered air i let in and accountwd for?"
