weird boost question?
Alright guys here's what I've got goin on. So I run the spd tune daily and cruising on the highway I see 10-15 psi depending on the road condition. Driving 35 through town I can see 5-6psi. Well today I had to go take my truck to the local dealership for an alignment so I switched it back to the stock tune. It felt like it had more power down low and I barely saw 3-4 psi while going through town at 35mph. and on the highway cruising 70 I saw 5-11 psi depending on the road conditions. Whats the deal here? Shouldn't this be flip flopped? Im running 35's on a leveling kit. Truck has 106,xxx miles on her. Thanks guys!
