Hi,
As tabs rightly says, if you give us teh number we can tell you waht its for, with regards a setup though, you get a lot for your money even if I do say so myself.

Our engine tuning covers things like:

• Compression pressure test.
• Cylinder Leakage Test (subject to above results).
• Intake system pressure check to 10psi. (More if forced Induction)
• Visual cam timing check.
• Spark plug condition and suitability.
• General ignition system check for condition and suitability.
• Spark timing.
• Fuel Phasing.
• Fuel pressure.
• Fuel pressure vacuum pull down.
• Fuel pressure positive increase. (Forced induction only)
• Fuel delivery at idle.
• Fuel delivery under cruising conditions.
• Boost pressure/s.
• ECU code analysis for errors logged and present.
• EOBD live Data stream analysis where applicable.
• Fuelling under heavy load in real conditions**
• Detonation Check under load in real conditions.
