perm open would cause it to overspeed and create extra pieces....

I`ve got mine plugged and haven`t had any problems and it dosen`t smoke unless I put in a higher tune. At about 300 ft down track it cleans up and dosen`t smoke with a 135 hp tune.

if you rigged the wastegate to always be open then you wouldnt make any boost....

you probably mean rigging it to never open, which also causes damage to the engine from not being able to dissipate boost properly when you let off the throttle


if you want to upgrade tuners EFI Live is the way to go if you get it from a good tuner, a Hot+2 isnt worth the money because anything over 100hp your tranny is on borrowed time, personally if i didnt want to mess with EFILive id go for an Edge Evo CTS or a PPE standard or Hot
