Had hg, head refurbed arp studs ect ect and it ran sweet pulled brilliantly but swapping to a 11mm fully resealed ect pump And seem to have lost power. Still boosts strong at 20-25 psi and seems to boost quick. No leaks I can see and no manifold leaks now but seems to be no pull anymore just smokes like f*ck. Just a touch under half way on pump bracket also. Any ideas? Could it be pump setup as therea plenty of smoke there so guessing plenty of fuel. I did notice a broken exhaust fin in turbo however only seems down since pump change

Lots of smoke black or white?
White more advance, black boost leak/issue
No smoke things to check throttle position on the splines, injection duration(smoke screw) lda in the same way.
Thats where i would start for basics
Tryd advance but with it knocking didn't give it too much. Black smoke I checked pipework seemed ok but ill have bumper off later check behind there
Did you replace the manifold seal when you refitted the exhaust manifold / inlet manifold, had heaps of issues with these before.
With more smoke then I would be thinking boost leak somewhere.
have you tried turning the jungle juice down? might be getting soo much fuel its getting abit upset and not burning properly
For the record. The head had gone smashed a precup up and 1 had spun. So only running on 3 cylinders essentially
I dare say that might cause some issues
