Installed an ATR 3" DP (stock style wastegate) last week and took the car to the track on Sat. I was consistantly running 103 traps @ 17 psi with the timing set at 19/21 on the stock DP. Mods are in my sig. I ran it with the cutout open and the boost fluctuated between 16 and 19 with the traps going down to 101. I was told stock turbo's don't like the lack of backpressure of a cutout so I capped it and ran 101 all night. Knock was minimal at 1 degrees, 02's around 750 and the boost stabilized with the cutout closed at 17 psi. I played with fuel pressure a bit and the car seemed to like 44 psi static.
I'm wondering where my MPH went. I'm at a bit of a loss on how to tune the car. Should I invest in an EGT guage and/or a wideband in order to tune the car better?
