Update to my feedback of 10/11/2015...

My car is a VY Series 2. I purchased the bored out throttle body & the 1.91 ratio rocker kit with pushrods...
Haven't gone for the memcal since my Exec is a 5 speed manual.

Have now had the car out onroad, before it goes in for the new diff & what a difference the new throttle body & lifter kit has made to the car's character!!

Straight off the line, it doesn't want to bog down at all anymore, instead it wants to go & go with minimal throttle I might add too!

It wants to break traction more than ever before too; and all without any kind of chip upgrade!!

Definitely satisfied with my purchases & I will be buying more of the same for my other cars...

Well worth recommending, and I shall be to whomever will listen!!
Excellent value for money!

I've recently purchased the high ratio rocker kit with pushrods & a 69mm throttle body for my 5 speed manual VY 2...

The kits were very easy to fit with everything needed as was advertised!

Haven't driven the car yet (mainly because I'm waiting to get a 3.45 diff fitted), but I'm looking forward to getting behind the wheel of it again because even in the driveway it's definitely got a new urge to get up & boogie!

Update soon hopefully... Thanks MACE Engineering!
Excellant products thanks

How a bolt-on mod should be.

Exceptional quality product - easy intallation and instantly noticable power improvement. Teamed with an 11 psi pulley and full exhaust (incl. extractors) the old ute absolutely howls. Definite difference to idle - lumpier but not overly so, just enough to know it's doing its job. Untuned the low down torque is much the same feeling as before but mid- to high-range shove is leaps and bounds over where it was. A day on the dyno I'm sure would unlock the full potential of this mod across the entire rev range but for now I'm more than happy with it. The quality, service and speed of delivery given by the team at Mace has been brilliant - looking forward to more additions in the future.
10/10 product

have found that the car has more mid range push , and a bit more down low as well , and it sounds a bit lumpier as well , well worth it .
