Jeez 
Lighting off the PT88...
Tuning my buddies turbo setup recently, He went from making about 0.6psi of boost to make 3 psi of boost on the footbrake with just leaning out the car below 5 psi and adding more timing. Tuning helps a ton. But then again, so does a transbrake. haha
9.0:1? I'd say your tuner missed a spot.......
Wasnt the tuners fault at all. We pulled it off dyno and had to fab to get tires to fit. I drove down to the shop and wanted to take it out on maiden voyage. During the little loop I stopped to try to see what it would do from a stop.
They looked at the tune since I hadnt let them dial it in on the street with the big tires. Where it footbrakes to is on a part of the map that you would never touch unless you did exactly what I did.
Thats why its called dialing in. I will report back to you guys. Car drove amaing cruising in traffic and partial throttle.

So I recently finished up my build and clearanced for the 295/55/15 tires today. Took it out and did some hits from rolls and all was great. Digs are another story...car cant even generate enough power to do a burnout (not that it needs to because it just HOOKS). Stall allows it to be footbraked up to ~2k, 0 boost. Mind you I dont have a two step, no trans brake. Ideas?

1) Dont use a 1250hp turbo in a 700hp car
2) Spray it.
3) See step one, and still spray it.

For building boost on the foot brake or transbrake and no two step (cause I don't have it wired yet) I had the best luck with keeping the timing higher and normal cruise/idle Afr of 14.7. Is your turbine twin scroll or just open? What size is your crossover?
We are going to adjust the timing and a/f in that region today hopefully. Turbo is open not divided. Crossover pipes are 2.25 i think? Whatever Huron Speeds are. Will update later.
