I totaly agree, people should be very carefull about choosing a tuner and there is not too many people i`d trust to tune my cars thats one of the reasons for wanting to buy my own.

You would want someone with extensive knowledge in your partictular ecu brand/carb type and engine config. And have large database of customers dyno files to prove it.

As you say, all this does make it hard to build a client base.

The dynos are about $75,000 if thats what you were asking. but i want to buy some In Cylinder Presure Transducers and software which adds about $10,000. These are for measuring in cyl presures when under load and shown on a graph showing pressure
during each degree off engine rotation. This allows for very accurate timing and fueling adjustments and shows up unstable combustion well before detonation starts.
It also plots exact BMEP/HP of each cyl tested.

for a sr20det dyno tune is normaly 500 to a 1000

its charged per hour

how much is a dyno worth ?
most people are very picky who tunes there car so not shore how much work u will get

How much does your dyno time cost you?

A bit of a loaded question as i`m contemplating buying a Dynapack dyno and was wondering if maybe i could recover some of the running costs but mainly it would be used for personal use.

Are you charged per hour, half day, is it only tune time or setup time aswell?
