Reduced power (limp mode) after upgrades
I just finished some upgrades on my 06 Vert. It already was running a Procharger (4lbs), full exhaust, fuel upgrades. It was running fine. I installed a smaller pulley (~6-7lbs). I should be in the 550rwhp range now. Also new wheels and tires (at 38psi). Now when I go wot on 1st or 2nd it goes into the reduced power mode. And I have to pull over and disconnect the battery to reset. I have done a search and nothing I found quite matches my problem. I read the tire pressure, or the traction control might have something to do with it. Or is it the loss of traction and it's hitting the rpm limit to hard? It runs perfect when I don't get on it. Resets every time. Any help would be appreciated. I know there are a lot of cars running way more power than I am.

Stock size 285/35/19 (Hankook Vetus V12 Evo). I just replaced stock wheels with the deep dish chrome Z06 style wheels (from forum vendor), and new tires. Fronts are also stock size. Ran into problems in past with different sized front to back on my 2000 WS6. So I kept to original sizes.

I had the same problem after I changed my plugs on my NA LS3 to NGK's...Changed back to OEM plugs and the problem went away. Can't give you any logical reason...but the problem is gone.

Do the tire pressure sensors mount in your "deep dish" wheels in the same manner as in the OE wheels?
Does the DIC of tire pressures correspond to the actual pressure in the tires (i.e., do the sensors appear to be properly programmed into the TPMS computer in the car)?
