hey guys

the time has come to weld up the gaping hole in my car's firewall
the car is off the road and with chrissy coming up i cant see a better time to take some action

atm its running standard ecu and dizzy, which is sticking through the firewall.
im looking to upgrade to coil ignition/aftermarket ecu for many reasons, mainly to seal up the hole and get some extra pace outta the motor, which is a silvertop 20v btw.

basically im after answers to these questions:
what are my ecu options? (im aware of the main ones, wolf, haltech, microtech, adaptronic so on)
Which one is best/cost effective/have/do you use?
what are the approx costs of the options?

im in Melbourne so if u know of any tuners that can tune selected ecu's that would be sweet to know aswell, otherwise ill probly hit up Trent at status tuning.

i think thats all im after, if i think of any other questions ill edit them in as i think of them.

ill just add that ive got my eye on the wolf v500 which is 1350 bucks

Thanks a lot guys
