So I have a 97 civic lx. I turbod it. Put 440cc injectors in. Walbro 255 fuel pump. Y8 intake manifold. And a chipped p05 ecu. With a base map tune set up for my car to get it to the tuner. The problem is it’s acting like it’s not getting enough fuel. If I rev the car slowly it will rev up. If I hit the gas fast from a idle it will big and then rev up. Same goes for if I rev it to 3 or 4000 rpm let off the gas then hit the gas again it will not rev until it comes back down. I’ve checked everything fuel wise. It’s all good. Psi is around 40

 

Its most likely your base map, put your stock ECU, injectors, map sensor and exhaust back on and see if it runs normal. Those chipped ECU base maps are garbage unless its a Hondata and a base map from a reputable company/tuner. Get a hondata installed from http://www.phearable.net/

 

Okay thanks. I’ll check into it. I put the stock ecu back in yesterday. With the stock injectors. I left the turbo on and the fuel pump in and the car wouldn’t even start.. it would just turn over. I put all this **** in at the same time besides the turbo. The Im I got didn’t have a tps sensor so I put a new one in. I thought I had it calibrated right. But maybe not. Could that be the problem? Or would it not be that noticeable

 

Yes make sure the TPS is calibrated, grab a multimeter and set the TPS to spec.

also make sure your using the correct IACV if you put a different Intake manifold on

Was the engine running fine before you put the turbo kit and intake manifold on?

 

Check your work. I left the stock ECU and injectors in mine the day I was going to the dyno. I had a larger in-tank fuel pump than yours and it drove fine for well over 70 miles without throwing a CEL.

 

I was going to say check the TPS as well. That seems to be one of the culprits with these swaps and modified cars.
