Member DKTOP has the following mods

HKS RS KIT Intake
3" exhuast w/ test pipe
Walbro fuel pump
Hallman MBC
AMS Tuning underdriven pulley
HKS BOV with recirculating kit

In this case we are not dealing with a car with extreme mods - just our basic every day type of street driven evo. The same car I tune day in and day out. I am posting this as a case study to show how hard work and long hours in tuning pays off with a smooth running and safe tune.

We are paying particular attention to this new crank pulley - in the past other brands have triggered knock activity

Here is our base flash - running a bit rich in this car - buit decent power - a typical safe through the mail flash

 

Here we are leaning out slightly

 

Step by step - slowly making "baby steps" to bring the curve in line

Note the significant power being made with a very rich a/f ratio

 

A little dip is left in the mid range and some timing adjustments to be made

 

Almost done - things falling in line

Decent power - a slight timing adjustment needed and the persistant dip at 5,000

 

That dip is persistant - almost perfect

 

Here is the final tune - totally flat a/f - smooth - knock free

To finish our day of tuning we will back this up with one more pull to verify that the tune is perfect and repeatable

 

Here is our final sheet - almost ideantical to the previous tune

Time for another test drive on the road to verify perfect operation

 

Great job AL ^^
you are rock!!!!
I am very happy with it.

Thank you and thanks Pruven performance.
