Holden VT VX VU VY VZ LS1 V8

For VZ 6.0L LS2 and L76 engines please view the VZ VE VF 6.0l/6.2L page
Please note, tuning is done in house on our dyno otherwise a

remote custom tune can be organized.


All figures are in rwkw (rear wheel kW) this is the power after it’s been transferred from the engine to the rear wheels. You may see other numbers used like HP, BHP, RWHP, WHP, PS, fwkW etc. Some figures are quoted at the engine and some are quoted at the wheels, if you are unsure you can always use an online calculator or please ask us.

We always recommend MAF tunes instead of MAFLESS (deleting the MAF-Mass Air Flow sensor), MAF tuned LS1's will allow for better fuel economy, better drivability, legalities and longevity of the motor. In the tune, we use the MAF for down low RPM and we tune it MAFLESS for top-end (speed density tuning over 3900RPM), best of both worlds!

310-340kw (engine)
240- 260kw (wheels)
