Unhappy ms2 juddering while holding revs

hi all,

just before christmas i crashed my mk1

begi turbo, ms2, 440cc injectors, GM AIT,

just this week i finally got the whole thing back in a new car.

All started fine, idles ok.

But through the rev range it judders when i hold the revs at any point at a constant speed.

Under acceleration its fine.

the afrs are all over the place when i hold the revs at most points but fine under acceleration as i said.

i was woundering weather the wideband needs resetting as the car ran fine before the accident.

if you could give me your thoughts i woudl realy appreciate it.

let me know if you ened more info

You has tuner studio?

Get the full version... turn off accel enrichments and other enrichments you might have.... turn on Auto Tune and go for a drive.... get some datalogs too. Try to hit all/most of the parts of the VE table.
