SV6 5spd tuning and gearbox shifts.

[treyflip]

hey everyone, i have 3 questions for the vz sv6...

1. is there anywhere in melbourne that can change the line pressures on the 5spd auto to get faster and harder shifts? price if possible?

2. if i bought the vcm software how hard is it to learn about tuning and applying it without blowing something up?

3. since i've already had a vcm tune but recently fitted cats and headers, can i go anywhere to get a touch up or do i need to go back to the place i had the tune done?

any help is much appreciated!

1. i dont think that there are many places that can do much to the gearbox, send MACE an email, they seem to know a little bit about it.
2. try starting a thread in the performance section on this site
3. more likely u have to go back to where u got it done, but it wouldnt hurt to call up a few places and see what they say

cheers mate, also i found that i was getting a rough idle and the battery voltage was showing about 13.7 on idle. took it out and ran it on another battery then put the old one back now its back up to 14.1-14.2. any ideas why? car felt like it ran alot better now.

no idea why that would be, maybe some of the electronics were not being powered enough and causing it to stutter, but yea i wouldnt have a clue
