Dinan Stage 3 Software & High Flow Throttle Body

[BMW-x5-48is]

Hey guys,

Got a quick question.. I am thinking of getting DINAN Stage 3 software installed on the car along with the DINAN high flow Throttle Body...

Do any of you have S3 from Dinan on the 4.8is ? along with the DINAN Throttle Body ?? and cold air intake?? Since Dinan does not make the cold air intake anymore for the E53 I bought the cold air intake from AFE - and want to buy the Throttle Body and S3 software from DINAN... Cost is close to 2 Grand for the whole package....

I cant seem to read anything on the Stage 3 update what it does exactly, except what my mechanic told me, that the stage 3 software aligns the vehicle's fuel maps to match the high flow throttle body. Otherwise the vehicle will lean out and the fuel mixture will be in correct, and that I should see more responsiveness and an increase in horsepower and torque.... Now the car has 80,000 miles on it... So just need some feedback do you guys think the Dinan S3 + Dinan throttle body are worth it?? or will it cause excessive use & wear on the car without much a increase in performance???

If anyone has stage 3 from Dinan & the high flow throttle body with a cold air intake any feedback would be greatly appreciated.... Is it worth it???
