Do I need to tune the ECU!!!!! 240sx

[janda240sx]

95 240sx Just swapped in fresh 40k mile KA. Before i put the motor in I Removed The EGR system. the only mods i've done is 4-2-1 header, test-pipe, 2 1/2in dynomax exh. cold air intake, removed the clutch fan in favor of dual hayden electrics. My car is running really rich now and the check engine stays on. Do I need to find someone to program the ecu for this or will it be fine?

Your fine. You could get aused safc and borrow a wideband and then lean her out to get some more power. But you have 0 worries of blowing her up. Unless you try to.

Any ideas om where I could find a Wideband. I'd like to squeeze as much power out of it as I could w/o a major overhaul on the engine while staying NA. Planning on upgrading the cams to a 264/264 setup later on.
