● The first run how it arrived was 342kw

● We re jetted the carby and changed some timing and it resulted in 381kw on 98oct fuel.

Anyone after some grouse catering hit him up best in the business 🔥

Thought it was time introduced myself,
(3 years later 🤷‍♂️)

My name is Jason,
I'm a concreter from a small town called pearcedale in Melbourne's southeast.

I grew a passion for cooking, living out of home from a young age with my partner and our
daughter,
watching the respect given to those who could knock out a good feed and the way they're loved by their families and communities was something i longed for.
Plus, being obsessed with flavour is also something that has driven me to become a successful cook.
Growing up camping around the Victorian high country cooking with fire was sometimes the only option and a true art within itself.

Bbq Catering is something I accidentally fell into after a few family cook ups and some good positive feedback from the right people, Anything is possible.

Every single time I light the fire, I learn something new ,whether it's about cooking or something about myself.

I strive to level up and change the game every time I do i function ,growth is the overall key to success.

Thank you 😊
Jase 🍻

Tristan's 408 ls swapped vk come to us having a few little dramas.

Suffering from detonation in high rpm and wouldn't idle properly

We adjusted cam timing as it was too far advanced, causing high cylinder pressures that wouldn't allow for timing to be added or the rpm required for the combo with 98oct fuel
We completed a full retune in house.
The car is now able to rev which it was in need of with the 5000rpm convetor fitted.
