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;)

Glad to see that worked to clear the code 54.


If the rear diff and the center diff are of different ratios you'll be putting the drive train under some serious stress the further out of sync they are. The front wheels will try and spin at a different rate than the rear wheels at the same engine speed. I wouldn't suggest driving it like that for very long/at all if they are of different ratios.

I'd be willing to bet that you're running too lean and getting boost limited and timing pulled due to knock response since you haven't upgraded your fuel pump. The fuel demands of a turbo engine are much higher than those of an NA engine of the same size.
