Do they both combine make a difference
Or is it either or.

 

I don;t think you need both ,but you need to let them know if you do have one , I have both because I got the booster first , hope this help you out

 

let me say this ,you get more Hp from the tune ,you do not get anymore hp from the booster

 

Try both and let us know. I wouldn't want to stack them myself as I already find the throttle too touchy with the Eurocharged tune.

Not sure I'd do both. I have the tune......which not only comes with added ponies but also great throttle response....

 

Yes same here the tune works awesome...im very happy..
Ill wait to see if any1 jumps in this threat that has done it

 

I have both, the Eurocharged tune and the SB.....and let me tell u what a difference the SB makes on the car! First I got the tune, made the car feel a little faster....but once I installed the SB....Holy Cow does it make it more sensitive and more responsive! Woke my N/A right up! I meant I know the SB doesn't give any horsepower but it sure does feel like it.

 

You can tune in a more responsive throttle. A sprint booster added pretty much will give you instant throttle response to almost instant full throttle. Which is too much for some. I love it. My wife hates it.

 

I got the sprint booster first and then a few years later got the Eurocharged tune.
I noticed the change from the SB more than the tune but the tune added almost 20HP to the wheels and as it is today I like having both

 

I have both on mine.
I actually did my Eurocharged tune first and I didn't think the response was good enough to blip the throttle for downshifts.

I would agree that it's a bit too sensitive for some situations though. Ex: Driving at low speeds in 1st gear and you hit a big enough bump to move your foot - the car suddenly launches forward.

 

That's happened to me when I sneezed....scariest sneez of my life! Haha

 

Damm It just happend to me with the sneezing.....I blame my allergies..but dam I bit scary wen my car took off
