Help with tune issue
I have a JLT cai and was running a BAMA tune. I bought a Brenspeed tune and installed it. Good tune and very smooth throughout entire power band. I took off my cai to clean the filter. I returned the car to stock and installed the factory air box while the filter was drying ( I needed to use the car ). Here is the interesting part. When I reinstalled the cai and reinstalled the Brenspeed tune it was very different. Where before the powerband was consistant, now at 3200 rpm's the car takes off like a rocket.
I decided to install the Bama tune again, then install the Brenspeed tune and it is consistant throught the entire powerband again. I called Brenspeed and they said if the tune is installed after the factory tune or any other tune it should not matter. Well, when I got home today I returned the car to stock file and then loaded the Brenspeed tune and I have the 3200 rpm "boost" back.
Has anyone else noticed something like this?
Stock file --> Brenspeed tune = 3200 rpm "boost"
Stock file --> Bama tune --> Brenspeed tune = smooth powerband
