Wanted your guys thoughts since the tune does a throttle re-map and adds horsepower and is $500 or get the sprint booster which just does the throttle remap.

 

Hi Buddy, I would suggest that you just go for the tune as it at least adds power to the car on the other hand the sprint booster doesn't make the car any faster it just improves the response rather add horses under the hood.

i agree, thnx!

 

I have the Sprint Booster installed on my car in addition to S3 Dinan Software. I feel they compliment each other very nicely.

so in other words get both haha! Dou feel that the power supplied by the Dinan software comes easier due to the sprint booster?
