What do you think?
 

With my current mods even the 60lb valve springs and 4gsk (when i put them on), do you think my truck could handle it if i added a #100 fuel plate and a boost elbow im getting a max of only 20 psi right now. I just dont wanna destroy my stock tc yet :c:
Plus another quick question why am i only getting 10mpg lately, do you think its cause i got the smoke screw (not star wheel although thats all the way forward too) turned in all the way, it didnt make a difference so should I turn it out and how much? I think i got it all the way in now :argh:

I dont think it would lol... my truck made the torque converter slip like crazy with a 100 plate full forward, and i saw about 40 psi with the stock turbo.

you've got other issues, causing bad mpg

boost leaks

X 2 boost leaks. Kiss stock tc good bye:tu:

How should I look for boost leaks? Is there any common places? and ya ill be getting a new TC soon, got any good brands to consider?

and i thought 20 psi is the stock boost? if it was leaking wouldnt it be lower?
