if you are seeing 1200f max egt either you are making no power or your probe is nowhere near the exh runners. if you're seeing max 1200c you're detonating or running stupidly rich. if you have properly beaded IC pipes worm-drive clamps won't blow off.
First, I have greddy fmic, it has properly beaded pipes, ALL do, without t-bolt clamps my old hose clamps would not hold up on dyno after 18psi. T-bolt have better clamping force. Second I use pyrometer egt f * 100 gauge from autometer, sensor taped on manifold runner off of #1 cylinder. Gauge goes from 0-16. Under heavy load never seen it go past 13. Made 380whp on dyno chasis with my set-up and a/f ratio wot from 4.5 rpm-8.0 is avg. 12.0, almost straight linear line. Car is tuned correctly and runs great on c16. Again I think Greddy fmic is very good, probably even better ones now offered in the aftermarket.
