I'm taking the Smurf to be remapped at the end of next week. I'm thinking that a EGT gauge might be a handy thing to have so I can keep an eye on the engine. Are the cheap ones any good? Seem to be about 20 quid on ebay.

It's not for tuning I assume they'll do that on the rolling road. It's more because I'm gonna be pushing the motor pretty hard and I assume the EGT's going mental could be a warning sign of imminent explosion.

You'll see peak egt several seconds after the event so pretty useless and they take a while to settle down , if you fit one put it in the downpipe and add a couple of hundred degrees to give a ball park figure , they will read ok up to 600 but fitted before the turbo they are rubbish .
A better test would be to put a boss in the manifold with a bit of steel pipe linked to a boost gauge and measure back pressure compared to boost to see if the turbo is choking

K type thermocouples (ie: those used in 99.99%of all EGT gauges) take about 15 seconds to reach steady-state conditions
