anyone got any preferences on the chips out there ive heard some good things about dreamscience
or is it even worth it ????

 

I put bluefin on mine, and although I could feel the difference it wasn't that much. The ST170 is already fairly well tuned and I think a car generally needs a turbo (Diesel or petrol) for chips to make any major improvement.
What I noticed from bluefin
- car picks up quicker
- slightly smoother
- the extra power/torque in 5th and 6th when cruising

Just my opinion

 

I had bluefin installed on my ST170 it was ok but switched to dreamscience shortly after and it is much better as its mapped to compliment the change in exhaust cam timing that i have. With my mods and the dreamscience im getting 189bhp soon to be 194
