What kind of boost controller are you using? Wastegate? Boost gauge? Sometimes its not the turbo. Hell all dsms do that.
Typically is a wastegate issue, the effeciency of the compressor wheel should not make the boost drop. And sweet congrats on the record
PS: it couldn't be the .63 housing being the restriction as all the examples i presented to you except for teh 1jz have all been on the .63 a/r housing. Unless there is too much exhaust presure causing the wheel to cavetate... but what are teh odds of that happening.
Hey whats your AIM name i would love to chat about this with you. Do you work for street flight? Or is it just a street flight project car?
