Just a quick note to let you know the differences in power ive experienced from my new GU.

When i got the 3″ exhaust done, I didnt really notice a ‘huge’ difference in power, the boost came on a bit quicker, and thats about it…It ‘does’ sounds HEAPS better thou… More like a Mack truck now, whistle and all.

The big power increase came from having Matt from QDAD work his magic on it. At this stage, the boost was not raised at all, just pure tuning. And the difference is amazing, its basicly gone from having to change down to 4th on hills, to blasting up them in 5th. Fuel economy has improved to boot! Once I get some 100% accurate figures i will post them, but for reference, its gone from about 15 to 13 / 100 kms
