Engine stops when deccelerating
 

Tried search but can not find any useful information.

Ok, here's the story.
Recently, I installed the Greddy turbo kit, with the e-manager ultimate and the blocking plate. Then the problem comes. The CEL'S on, the code is P2070. I cleared the code with AP. The engine will occasionally stop at idle or when I decelerate to 20-40KM/H. Also, it's hard to start the car when it is totally cool down.

Does anyone know what's going on? What should I do?

Thanks!

I'm going to say this first. . . I have no experience with turbos or tuning, but I've read how important having a proper tune is for the RX8...

Do you have a custom tune? Upgraded fuel injectors? Upgraded ignition?

(Really, you'll need to wait until one of the turbo-ed guys comes in here, might want to ask the mods to move this thread to the major horsepower upgrades section for more exposure.)
