MassiveMods Best advise on how to modify a temp gun to give you the best readings for tuning.



1 Get temp gun and place on firm surface
2 Put on safety goggles
4 Select heavy hammer
5 Repeatedly hit the temp gauge till it looks like the pic below
Please refer fig 1A
6 Use temp gun and see how well it takes temps now.


Now that we have modified the temp gun we can use it to help us tune the engine!

Hope this helps !

Cheers MM
