MACE VS commodore memcal and soon to be review

Well i am just kind of going through the car and replacing stuff that it going to help with Fuel economy.
So far i am seeing improvements in Avg fuel consumption, but ideally i want to test on a FULL tank of 98 ron. This is 3/4 tank 95 RON.

I also want to change the Plugs (BFPR7E-13?) 1 step colder? Is this ok for Stock boost?

 

Fortunately quality O2 sensors have come done in price over the years

In regards to running colder heat range spark plugs, DON’T! They’re much more trouble then they’re worth!

 

hey just a question will a vs trans fit in a vt?

 

I'll will. Worse case you'll have to swap the looms and electromechanical items (force motors) between gearboxes. The later is something that we've have to do to get an VX V6 gear box to work with a VR V6 PCM in the past.

Hope this helps

Kindest Regards,
Steve
