boost issue ?
So it’s a 2.5 fsti , the elh split , it was welded and it appears fully sealed , it was bolted back on , it now won’t boost , if you go 1/4 throttle it will max rev and boost gets to around 1 bar , but if you floor it it hits between .5 and .7 bar then shudders and won’t increase its boost , plugs look good , i’ve ecutek and disconnected the battery over night to reset it but it’s still playing up , no sign of any cuts in intake or boost lines , plugs look good , last job is test the fuel pump pressure , any thoughts please

it’s a valid point , but they were good before it was mapped as that’s about three years ago , leak is recent , i did an ecutek ecu reset , don’t know if that would work , i don’t think it’s an ecutek map , i’ve discounted battery and leaving it over night , maybe issue is resolved but still playing up as the ecu has not reset , boost is good to around .5 of a bar then goes wrong , max boost is around 1.25 to 1.3 bar

cheers for peoples advice , so took the plugs out they looked fine , i changed them any way and where the positive lead bolts to the battery gave that a clean too as i had moved it earlier , fingers staying crossed it’s all back to normal now pulling like a train , it’s 5 th and 6 th boost drops of slightly but power does not seem to but i think a small loss of boost is normal , very strange plugs looked hardly worn or is was the battery connections , maybe taking the plug out before was it’s down fall and it was not sealing in the head as well , who knows but fingers staying crossed , new elh ordered from hayward and scott 1050£ ouch 👍
