    Default Friends 1g powerlosssss....?

    My friend has a 1990 laser with the stock 4g63 2.0 turbo.(14b) The guy he purchased this car from claims to have put 550cc injectors (factory fuel rail) walbro 255 fuel pump and a python injection ecu. I rode with him the other day and right at about 5k rpm's it just creeps. He never has taken it past 6k but to get there from 5k it took a minute. It just struggles and is so sluggish!! It does not jump or skip or anything, it's still smooth but very sluggish. It has an aeromotive fpr. Does anyone no exactly were that should be set?? He has it at about 40-45. somewhere in thatrange. He's a frusterated s.o.b. right now. Any help would be great. i think it has something to do with fuel. Does the pump need a rewire?? any diagrams?? thnx!!

    I had the same car with the same problem. Mine was the throttle body idle screw. They are cheap ass plastic screws that get worn out and stripped and it causes bad leaks.
