Mark J. has my 06 Paxton Coupe right now for some additional mods (Quaife w/ 3.55s, 08 Hood, etc. ). He suggested a wideband to keep an eye on the AFR. Here's the gauge they are installing in a MBX pod on the steering wheel. You can probably find a pic of the pod here, I know HISS has the same pod. I'm not aware of any A pillar gauge mounts for the GEN3 cars, and I wouldn't want anything stuck to teh windshield.

Good luck.... , and additional mods? Sure, do the Quaife w/ 3.55 gears now while your car is there, or wish you had for the next year until you finally sent it back for one... LOL
