So I went out of town today and realized I am only boosting 8-9 psi. No matter what I did this was the max. So I figured maybe my MBC works a little bit so I cranked it all the way up thinking that should give me my 10 psi no problem... Sure did and another 4 more!!!!!! lol I got on the highway and punched it, looked up and it was holding steady at 14 I was like HOLY ****!!!!! Naturally I let off the gas right away. Turned it down halfway and still hit 13. My CEL was not flashing at 14 so thats a good sign. Might try to get it adjusted to hit 12 and go tuning
Stock internals and all to right?
Im going to install the MBC when i get my new turbo, it will be here tuesday, i still have to "mod" it by shaving it down to fit, but hopefully this turbo will last a little bit longer haah, with my blown turbo im only getting 4 PSI max and i think thats even fun! i can only image like 8 or 10 haha!

Ordered my S tech springs, $180 shipped, not bad at all, tracking shows it will be here thursday, cant wait. Another note I got my boost controller dialed in at 12 psi woohoo its pretty sweet. Definately noticable difference. Fuel is a little rich around 10.5 but no knock at full boost so I am not messing with that for now. Need to log for more in depth view of whats really happening and wont be pushing it as hard as I did tonight until then but very pleased so far.
I notice that I get what senate was talking about that flat spot around the 4000 range. Like my afr's go from 10.8-11.0 and all of a suddent it jumps to 12.5, then after 4500 rpm it drops back to 11.5.
so I think im going to mess with the maf scaling a bit and see if we can get that taken care of and mess with some timing as well.

hey 03lance I noticed on your fuel map that you have engine load percentage at 100 110 120 130 etc... mine goes from 100 to 120, 140 160 etc increments of 20 besides 10.
how would big of an impact would that make by me changing these variables and tuning as I go? And do I do the same for timing as well?
and here is my fuel map plus the 3d map
