so far I have only driven it once, but it hauled some ass on just 9psi of boost(wastegate spring pressure on the Tial 38mm gate)...fried an injector driver because I used injectors that werent reccomended for my setup...so I have to get my computer repaired before I get it running again...another 2 week delay(has to be sent to CA and back again), oh joy, but since it was my fault for not getting the flyback board to begin with I only have one person to blame, this time its getting an upgrade to relaibly handle low impedance injectors
