Well Cossie friends, I would like to hear from guys what you would recommend as the next step for my Cossie?

I have a Sierra Cossie, 205 block YB engine, 380 hp chip from Stu (MSD) on L6, t34.55, uprated t34 actuator, Deka 55 lbs, 3 bar map, Bosch 044 (Rewired), Ford 071, Cosworth HT lead set, Ford RS Cosworth & Turbo uprated Ignition Coil (GPA), RS 500 style intercooler, Group A head gasket, AP Racing Group N 3 plated clutch, FuelLab fuel pressure valve, K/N airfilter, GGR Silicon hoses, Group A air intake system, Group A cooling system, Group N bushings, Rustfree oil reservoir oil breathing system etc.

If I want to get more be quicker/faster acceleration/more power, and use as many parts in my setup as possible (as they are all new...) what could I do?

- Can I raise the boost? The chip is setup for 32 psi, I am running the car at 32 to 34 psi but few sec after it drops to appr. 25 to 27 psi, which is normal for the t34.
What can the YB engines take in boost? If the head gasket blows, cant I use ARP bolts or similar and boost more?

- Bigger turbine?

- Lower diff ratio? I have Supra 3,9:1 diff ready for install and will use Toyo R888 tires.

- Anything else you can think off?

Any good advices or tips greatly appreciated!
