Make sure also you have no vaccum leaks.

 

Check your alky kit. Make sure its not activating at idle.

 

i think u might what to get a better management system because ur car wont run to good with the factory ecu but it is possible though

 

if u look in the Dynoflash threads, AL is flashing a 2.3l gt35r evo 9 with over 500 hp , so i think a flash is fine as far as management systems goes. i had many trouble with my vta bov on my golf when i had it. its something that u can swap in and out, so it might be that and if its not then its not like its hard to reverse it.

 

I would also check your fuel pump. Maybe swap you stock one in just to make sure its not the problem.

You really need it tuned bad. Your ECU is tuned for the stock turbo so there is a good chance your running really rich in the lower RPM's.

 

will it start up and run if you hold the throttle? if not, you might not be getting fuel.

and i 2nd checking that alky kit....when i installed mine it sprayed for no damn reason because the controller was fouled
