You'll get a little fluctuation here and there. Its nothing to be alarmed about, thats the mbc spiking a little.


Best bet is the log the car to make sure you're not knocking.

Cheers!

You should be ready to cause some trouble then, cars running good!

Nope... Typically you want to set boost in 3rd gear on 5 spd cars and 4th gear on 6spd cars.

Cheers!

how much boost can i run with 93 oct and can you tell if knock is occuring if not on dyno but just by listening to the motor.

what rpm in 4th gear
to set boost to 24psi

The amount of boost all depends how the car was tuned. I would call Buschur to see what they recommend, running alot of boost doesn't always mean the most power...


Only time you'll hear knock is when its a pretty high amount that could damage the motor. With a tactrix cable and Evoscan you can log the car to see exactly what its doing. Just find out what boost they want you to run and I'm sure youll be fine.

The car will boost higher, depending on the rpm and load. As load increases with higher gears, the boost will follow.
