Greeting Minitorquers:

I just finished swapping my stock engine with a JCW engine.
When I went for my first test drive the car drove half way around the block and shut itself off...
(It seems like its protecting itself.)
I'm running a stock tune with the bigger 380cc JCW injectors... (15% pulley)
could this be the cause?
do I need a tune to run the bigger injectors?
The car Idles fine and seems to drive normally for about a minute...
The problem always seems to occur seconds after a small pull.
the car comes back to life after a couple of hours of being turned off.

I think some people are running the 380cc’s with the stock map and have no issues.
Your problem does sound strange. Someone with more knowledge than me will be able to help.

I swapped out the 380cc injectors for the stock 330cc and had the same result, the car is running perfectly fine...
I did a amall pull (nothing crazy) soon as I took my foot of the gas the car stopped...
I cranked the starter motor and it sputtered to life for a second and clunked out...

What happens if I have pre-destination? Does the engine shut itself down?
