Error 54, Does error 54 on the st205 slows the car down? Options

[Rav4Race]

Hi guys/gals... I own a Rav4 model year 2000 and ive swapped in a 3sgte st205. The engine seem to be perfect but however my check engine light is on... I bridged E1-TE1 and ive detected an error code 54. Ive read in a message posted by insanity on 6gc.net, where he proposed to bridge the coolant level sensor, which i did! But the problem is still persisting, my water pump is working.
Well guys i need help, i dunno if my car's boost has lowered because of the 54 error code? Or is it that i havent changed my fuel pump which is holding my car back? But Rav4 use a 2L fuel pump, n i doubt that this is the problem. Plz advise me:(
Another question, after bridging the sensor, should i take out a fuse or something just to delete the problem from ecu memory?
thnx for all;)

I have a Carlos Sainz Engine and ECU, and I set up the water pump in on my WTA to run constantly, and I tricked the ECU by simply installing a resistor between the INT wire and ground. This got rid of the Error 54 message... The wiring diagram up there looks more complicated, but probably is correct for that ECU.
