RB25det HELP NEED HELP

[drugsbunny]

Okay i just finished dropping in a R34 RB25det NEO 6 into my s14 240sx. Everything is wired correctly we triple checked everything. I can start the car and everything seems fine. I can rev it to redline without any problems BUT When i try to drive the car it doesn't go past 20mph. the gas pedal just starts feeling soft and it doesn't work, after a certain RPM the gas just cuts off. I had a stock fuel pump before and i couldnt go past 2mph, i upgraded to a walbro 255, and now i can at least reach 20mph. I have no idea what the problem is. I adjusted the TPS sensor already. The MAF seems to be correct according to the nissan FAST program. soo i have no idea what the problem could be.

Any help would be appreciated, anyone that lives in the chicago area and can fix it let me know. i will pay. just PM me.

Fuel lines crossed maybe? what bout your ignitor's? Throttle cable?

No the fuel lines arent crossed, i checked that already throttle cable is fine since the car revs perfect when its not moving.

PROBLEM FIXED!

The problem was the MAF wires were to thick, there was to much voltage going to the MAF, and it was throwing everything off. I put the correct wires and the car runs perfect.
