Just a few quick questions...

1. It depends on many things, sometimes after tuning you may make too much or little boost and or the fuel injection timing and flow may have to be adjusted most importantly do the egr tuneup beforehand!
2. The factory egt sensor maybe fine but you can also mount a pyrometer onto the exhaust manifold to measure heatsink which Rawze has a video on his page
3. Engine serial, CPL, cam timing
