No it's not, but if the wastegate is capable of flowing enough to control the boost pressure, plumbing the actuator directly to the boost source will control boost just fine, at the expense of response and possibly boost up top.
Yes, changing to a high flow cat without supporting boost control mods (ie wastegate porting)
But a blocked cat will cause an exhaust restriction that will hurt boost.
Yeah I have a probe but don't bother using it for steaks etc. I don't used the dome Temp gauge as it's proven itself to be fairly inaccurate.
I'll give the deflector plate ago. Wifey is keen to do a chunk of pig for pulled pork dishes so don't want to cremate it.
Thanks for the tips!
Just the top and bottom vents and charcoal placement to control temp.
Mine drops intially but then roars up once the lid is closed. I cooked some steak on it last night and used a handful for charcoal and it still does it.
This gets me all the time. Mine rises slowly and tricks you into thinking it's stabilised then will spike once you put the food in. I think the time it's open must draw enough draft to get the charcoal all stirred up.
That picture actually features another well known WA Member. Those who know who it is keep it quiet. Those who don't are free to try and work it out.
Let me just say he might be a tad touchi about my posting it....
Those figures are normal. Tmap reads absolute pressure so atmo is around 14.68 psi and boost is atmo plus boost pressure so in your case 15 to 16 psi boost plus atmo = 31ish at full load.
