[QUOTE="bluebullitt256, post: 9678378, member: 100496"] The secondary air injection is for emissions purposes only. It just pumps air into the exhaust manifolds upon initial start up to help heat up the cats quicker and reduce emissions. Deleting the egr will slightly effect fuel mileage but it will reduce the amount of crap being sucked into the secondary intake ports from recirculating exhaust gases and unburned fuel, etc. etc from the egr. Trust me look up some pics of the intake with the egr and then with it being deleted. Its much much cleaner without the egr. Deleting both of them will have no negative impacts besides slight mpg difference. Just make sure you get a tune to turn both of them off and your engine will never be able to tell the difference.
