UTEC tuning vf39

[subaru20t]

My 2004 WRX is in the shop now, I wrecked about 2 months ago and the insurance company finally paid the shop and they started work. The body is all fixed, but the timing cover was hit and the timing belt must have moved out of time. So now all the valves are bent, the heads are done, but when they were putting it back together they noticed the prop shaft in my turbo had some play. I decided to go with the vf39 for its replacement, also added 565 deustworks injectors and a walbro fuel pump. I already have turboback exhaust, up pipe, intake, and a turbo xs UTEC. I'm curious if the stage 4 map is going to be alright to run until I can get a custom tune. I know i'll probably need the intercooler to complete the requirements for that map, but I need to drive the car in the meantime. Any advice on this would be greatly appreciated. Thanks.
