I've tuned a 2009 ZR1 today (pulley/headers)
On the dyno (5th gear, the 4th was too much for the dyno), the MAF Hz can't pass the 11550hz (@5000 rpm) and then ran pig rich.
WTF ?
The Table goes to 15000 !

Can't really confirm but it sounds plausible. I can't remember, can you command the Fuel Pressure up anymore via the fuel system section in the tune? If you can get the pressure up and the Duty Cycle down then test it you'll be fine.

Update : We ve changed the injectors.
The ZR1 has gain 100 rwhp and rech 997NM torque on the flywheel
there is more in them! My best did 824hp and 1135Nm at crank when blower ist completely maxxed out.
it is a beast, all you need is 1st and 6th gear, all other gears are purely optionial!
