I have a sprint booster for an automatic E60 for sale. $125/obo shipped. My car does not seem to like it . I keep getting engine malfunction and soft throttle response. I am guessing it is my car not responding to the Sprint Booster. Will post pic later.

 

That seems odd ... are you sure the SB plugs and pedal plugs are lined up correctly? That mess-up is easy to happen.

 

Yeah I tried mutiple times. Did not work. Maybe it me not knowing what I am doing.

 

Did you check the pins and make sure all are straight (not bent)? That happens too. GL with the sale.

 

Yeah they are all straight and sturdy. I think it is my car. Plan on getting the Dinan stage 1 upgrade while they have a 20% discount on software and see if that works.
The booster is sold now so time to move on to the next thing
