im running no boost controller any more, and with an exhaust, and front mount, my gauge reads .5bar for the first turbo, and about .8 for the 2nd... i figured stock would be less, but wasnt sure how much less.

hmm.. how did u manage that? id like mine to be able to read 12psi or so on both turbos, thatd be heaps better... but 13, then 10 is kinda odd.. unless u want it that way?

i could be wrong,
but sounds like an exhaust restriction is limiting the top end, Confused
maybe someone can clarify

yeah that could be the case, but wouldnt it restrict the first turbo too? maybe the actuator isnt working like it should.

lol i dont mind mate, be insteresting to see if it works...
i wouldnt mind putting my EBC back on, but on my last engine it was on, it wouldnt go higher, or lower than 1.2 bar... so dont really want that, might get it tested.. or i think the actuator on my last motor was bung...

Mine is always around 10psi stock (with dirty pod). EBC, clean filter, FMIC and larger exhaust soon fix that though Smile With my supra soon as I put on the exhaust, FMIC and pod it went up to around 14psi.

Usually just the 2nd, 1st I've found is always less.

both turbo's aren't efficient enough to run the whole length of the power curve unless ran in true twin...

comes in harder but later... with an upgraded stall, its a good way to bypass the various VSV's and make it all a bit more predictable...
