High idle
High idle Had my car dyno tuned at a shop using a Predator. Good power after dyno tune. 390 rwhp. The problem is that is idles very fast. Just over 1,000 rpm and when I let off the gas it doesn't decelerate like it used to. Auto trans. Used to stall a lot before dyno tune so the shop said they turned up the idle to prevent this. Is this normal?

My fast intake did the same thing, when you installed it did you replace the valley screws with the ones that cam with the fast intake? If you did then make sure the intake is tight and everything all the way to the lid doesnt have any leaks. Last call the shop and ask them if they turned up the idle
