But my issue I've found is my brake boost function is no longer available after the install I'm gonna check my botls and nuts today just to double check physical problems. But when I watch it on the laptop it shows I limit at 2000 rpms with 18 percent fuel trim(stock)and it just holds me there then i leave the line like a hurt dog , is this maybe trq management ?before the install I could almost spool up 10#s of boost off the line with stock turbo understandably it had very little lag but I would be able to rev past 2000 rpms. So any help would be appreciated. Boost junky if you are out there help me please . I'll post and on/off log of an attempt
