I have the TRD 44cc Injector on my car because I just took off the SC. Can I run the 440's with a stock ECU?

 

you will prolly throw a rich code, seeing that there is less air without the sc. im sure u CAN run them but your car prolly wont run as strong with an impropper air/fuel mix.

 

No, your car will idle with a violent shake! Well at least it does with 550s. Trust me I know...

 

I agree, it may not be as violent as the 550c's RSracer had due to the smaller size injectors, but it will have a violent and uneasy idle to say the least. Not a good idea to keep them on without the supercharger.

 

If you have a flashed ECU then yes you can run the 440cc injectors without the blower...but you have to keep the SC air-box that the MAF is mounted to.

If you replace the air-box to the stock model then you need to change out the ECU and change out the injectors as well.

There is a post from Garage witth info that will allow you to re-program an ECU off a doner vehicle. You need a new non-flashed ecu to go back to stock.

 

i thought the kit came with 400cc, not 440's...
