LS1 Throttle Response issue

[gjkrv8]

Thats what I like about this forum - very helpful advice plus some healthy Chev/Ford debates without people taking offence.

Thanks for the suggestions so far.

I am gradually working through the problem by proecess of elimination.
(Fuel pressure ok, plugs changed, plug leads changed, coils seem ok).

I think its driveable enough (for my Engineering on Monday 8th).

I just hope the emissions are still ok with (what I think) is the tune being off.

I might be getting a loan ECU to try beforehand which might solve my problem as my original ECU might have had a dodgey Tune in it. We only just removed the VATS and adjusted the HS FAN temps.

Will let you know how I go.

Any further suggestions (other than a swap to a ford engine ) are welcome.
