C6 Z06 LS7 Stage 4 tuning problem

[Berlou25]

Hello, i'm new on this forum,

I have problem with my Corvette c6 Z06 2006 after stage 4 install. Install himself because i'm from France. I have a map from Race proven Motorpsort. The car starts well (better when cold) and keeps idling well, but if I touch the Accelerator, the engine revs too low or stalls.
I tried a neighborhood tour, but the car shakes a lot at low speed (between 1000 / 2000rpm)
The richness at idle is top (lambda at 1) (Lambda probe on external box)
I suspected an intake leak. I completely disassembled the MSD intake and reassembled with joint compound on the joint faces. But same problem. SO i think it's just a problem of calibration.


My configuration (just mods rest is stock):


-280cc cylinder heads from Race Proven Motorsport
-Camshaft B3 (243/259 at 0.050 lobe separation 114 lift 0.666 at 1.8)
-2 "ARH headers with catasport and Borla catback.
-103mm MSD intake with 103mm Nick Williams TB
-HALLTEC killer Bee MF108 air filter
-60lb fuel clinics injectors
-Monster clutch S series bi-disc clutch with lightweight flywheel
-ATI Damper Pulley without overdrive

Somebody can help me?
Log and calibration (base and rpm cal) in attachement.

Thanks

Just a guess, but you could try increasing Final Airflow Minimum. Not sure what you meant by "The richness at idle is top (lambda at 1)"
Lambda 1.00 is stoich so that would be pretty good.
