Just installed 880cc injectors and have yet to get a tune.
When I drive and reach 10 psi it's like it hits the fuel cut. But if I sit there in neutral and rev out the car it seems to be fine. I ve heard that I only need a tune but I'm not sure, any suggestions on what my problem is

 

The car needs a retune to properly scale the injectors. Driving vs. just revving the engine, the car is seeing different loads which is changing how much fuel it should be dumping in. Get your car retuned and itll be fine.

 

As noted, get a tune & for sure stay out of boost. Drive it to your turners in vacuum only

 

Ya bad idea on driving with big injectors without a tune. Either install your old injector for dd and then when you are ready for a tune, let the person who is tuning it install the injector or do it yourself and then tune the car with the new injectors.

 

so a tune will fix my problem

 

Yes

 

And yes a tune with fix your problem, like the other member suggested.

Will ask yourself a question, did you have the fuel cut problem before you put the bigger injector?

And always you should get a tune if you are putting bigger injectors.

 

Doubt it'd be fuel cut that happens when load limit it exeeded by xxx ms. This would probably running so rich the mixture can't ignite.

 

Why would you be trying to boost without a tune like stated above put your stock injectors back in untill your ready to get tuned your injectors need to be scaled and tuned in stay out of boost and get a tune problem solved good luck man
