Hi guys, I'm considering to get preve exec.

-Is the fc that bad?
Some say good, while others say that it's horrific. The data in fuelly is kinda varied. Some 7km/l whereas some is as good as 13km/l if I'm not mistaken. Saga blm full tank can go max 300km (rare occasion). So anything better than this is good!

-Weight to power ratio? Any problems with steep roads?
I remember a popular post in LYN saying that preve exec couldn't climb up genting or steep hills and this worries me. I asked SA and it's only logical that the SA says it's not underpowered. Is this problem resolved?

Pick up?
- I use to drive a saga blm 1.3 and the pick up is quite bad. It's famed that proton is underpowered below the 3k rev. But I do pray someone here can tell me it's not the case for preve exec!

-Will it void warranty if I were to change the headunit? Some say cut wires = void but some say no problem. Mixed answered from prevec fb group.

Thanks for your reply. My replies r the underlined parts. I hope an executive auto user can shed some light as well
