The highest I have seen with my '03 is 26psi and 1250 degrees pre turbo. Stock engine except for the airbox mod.

stock boost is 22-23 when it is summer temps, winter temps in the 30's will run 23-24lbs, egts are 1225 on a 70-100 mph run.

the 555 engines will make ±25psi boost, while the 600 will make the 30+ boost

±1200° for the 555 pre turbo, ±1300° for the 600's pre turbo

Hey Blue,

Did you mount your boost tube in the horn or using a boost bolt in the maniford?

Thanks,
Mark

Will a boost gauge yield different readings between these two installation methods? I was going to go the easier way with a boost bolt but if there's a question about accuracy, I want the accurate way!

I'd think that being in the manifold using the boost bolt would be more accurate, but thats just my thinking..
