Is it common to set up an exhaust gas temperature (EGT) meter and a probe for EACH seperate cylinder in order to get a pricise tune?

In fact, if you just monitor AFRs, is it even worth it?

I am boosted near 600whp currently on a mase kit, and i'm running hondata flashpro as my ecu and I have an AEM UEGO wideband.
My new possible tuner (who supposebly has over 15 years of reputable experience) says he wants me to get them for when he tunes the car after hes came across issues with my exhaust valves being burnt, etc. that hes fixing.

I've never heard of this being a common or needed thing, especially if im getting wideband readings, so I just want to make sure my money would be well spent.

Have any of you heard of tuners monitoring all four cylinders with seperate egt meters for tuning eventhough the car already has wideband and flashpro ems?

PLEASE GIVE YOUR INPUT thanks!

 

the request for 4 seperate EGT confuses me, it just seems like a waste of money and not necessary as you have a wideband.

Mase tuned my car with his kit and never made a request for even a single EGT sensor, let alone 4.

 

I understand, and thats what I thought too. But then I took apart my exhaust manifold and cylinders 2 and 4 had a crap load of carbon buildup, #4 seemed normal, and #1 barely had any carbon residue at all! Since something is causing unequal flow the idea of having 4 probes set for each cylinder to monitor egt's comes to mind. We could be able to pinpoint problems more pricesly like this.
now is there another way to do it without spending this much money? I hope so, and thats what Im trying to find out.

Keep in mind i also had some burnt valves and was getting some occasional misfires contributing to knock count. not good. whatever it is, it needs to me looked at more. because, like you, my car was tuned by MASE too, and yet I have all these problems. Im not saying its his fault AT ALL, but i am saying something is going on that needs to be looked at more extensively- otherwise im sure mase would've told me whats causing it...

 

then if you must monitor egt and if you want the data to be more useful then just an wideband, I guess you have no choice but to run either 4 seperate EGT or 4 seperate widebands in each runner.

I hope you get it all sorted out, let me know what you find.

 

i dont think that it is necessary. a good tuner can usually tell by the spark plug wether a cylinder needs to be richened up or leaned out by the fuel ring on the plug. Also to help with cooling the cylinder possibly. typically middle cylinders run hotter or leaner from my experience.
