Fitted S.E.C.S monitor and have lost boost????
 

I fitted a secs monitor to my car at the weekend, I checked the Fault log and cleared it of one fault which was exhaust gas temp sender to high, I've gutted the uppipe but havent yet fitted the required resistor to stop throwing a CEL

When i reset the ECU does it take time to re adjust knock correction, injection timing, timing and boost. I've checked all the hoses i disturbed whilst fitting the oil temp sensor on no. 3 cylinder.

Is there somewhere else i could check
It was running 1.35 Bar now only 1.26 Bar

The car is an 02 WRX with APS FMIC APS KAC and a Tec 3 Remap

Thanks guys in advance for any help, Aston
