Hi guys,
looking for some advice here. I have a ba xr6 turbo BTR running on e85, with a gtx3582 turbosmart 12 psi actuator, flapper mod, walbro 525, gfb regulator, bosch 1000cc, plazmaman 800hp cooler, support mods on engine including spools rods and all the bolt-ons.
I started tuning the car and all went pretty well until started creeping into 19 psi of boost, after this stage I started noticing a cut at 3500-4200 rpm. After spending some time on the datalogger I found that my torque source was coming from the transmission and not drivers demand. I have tried quite a few things so far and can't seem to find a solution. I have followed the thread HOW TO stall up your automatic that gave me some ideas on what the problem could be but still no luck. I'll attach my tune and the datalog. I'd highly appreciate if someone could shed some light into this.
Note: I haven't yet adjusted my speed density tables and don't really know if I should do anyway.
The cutting issues is happening at 406 seconds into the log.
thanks in advance.
