Sputters and coughs under load

[Paul Clark]

New turbo and injectors, downpipe, plugs and wires.
Also turned the coil pack around (it was backwards) and reconnected the wires to the proper posts. Car starts and idles great and is very responsive in neutral.
When I lock the brakes and try to build a little boost it sputters and coughs.
Ideas?
Thanks

I'm having the same problem and need some advice also. Getting the coil pack and ignition module checked now and from there I'm not sure where to go

See my other post about data analysis help.
Did you change anything on your car? I made several changes, so now I'm kinda "chasing the rabbit".
I'm trying to eliminate variables.
All I can think of is that I have a possible vacuum leak where the boost gauge is spliced into the line going to the dash boost sensor. Could that cause it?
Going to try a different chip tonight and will see if that makes a difference.
Keep me posted and I'll do the same.
Good luck to both of us.

Interesting.
I put in my old chip (for 009s) even though I now have 50s.
No more hesitation in gear and I built 4+ lbs of boost with the brakes locked in the garage - I quit before it went through the back wall.
