Maptun upgrades

[aero]

Hi!

I noticed that with MapTun you can get 280 bhp from a £1100 upgrade. Firstly, assuming good dry weather, how much would that make the 0-60 time decrease, bearing in mind it's about 6.9 secs on my standard 9-5 Aero?
Second, would you need to modify the suspension and steering as well? How much would that cost?

I need my car for another 3-4 years so any performance mods should be worth it!

Thanks

Your 0-60 won't go down that much as there'll still be traction issues in the lower gears, so you can't use all the power you have. The mid-range power will be impressive though.
