I was still getting 115 or so when I was bone stock on the stock 18" hollowspokes. Unfortunately, I didn't do any runs with the stock 18"s and the exhaust. The 19" wheels hurt your trap speed as they are more rotational mass. Rotational mass is a bad thing when you are trying to drag race (which is why most go with lighter wheels/tires, flywheel, driveshaft, etc). Even then, I still hit 116.25 with just an exhaust (good power gains) and the 19" wheels (hurts your trap speed).

Do you still have the stock diverter valves? Perhaps a small boost leak? Exhaust will really help you, however. It will allow for the turbos to spool more quickly and breathe easier.

 

Yeah im set up about the same as the OP, but I have a problem where im boosting about 1.3 bar pretty often. Im waiting to get into evoms for the cure.

 

I have the EVOMS Diverter Valves.
I I never see anything above 1.0 bar

 

Ruiner, it is his first time, let him get a feel for it, better launch, shift points ect. He will get better times, just needs some practice....
