I removed the ecu on my93 to see if it had been chipped and it has a Bozz Speed chip fitted which was giving me 1.1 bar
i just took the car out after replacing the ecu and am no longer hitting 1.1 bar
It boosts to 1.0 then drops off to 0.9 bar and doesn't pull as hard...Gutted!!! Any ideas why this is?

Regards ossett

 

why did you replace the ecu? that is obviously the boost problem

09 is standard boost u may be overboostin now causeing the car to cut the boost back to protect engine

 

disconnect battery for about 30 mins the n reconnect and try it again
