stutter after chip install

[Brawnyrebel]

I just did a 4"turbo back and a tw 6pos chip on my 96 and when i step in the throttle it seems to stutter unless you ease into it. Kind of like it is running out of fuel. I assume it could possibly be the clutch which is a newer single mass luk but it never gives off the burning clutch smell. Has anyone felt what im talking about and what resolved it?

Did you make sure the contacts were clean enough before you plugged in the chip? Does it do it on all settings?

[Brawnyrebel]

Yes i cleaned the contacts very well. It does it on street and extreme the most. once the turbo is spooled it seems like the power is there and smooths out.

does it do it all the time or only somtimes? do you have a lopey idle also? mine has the stutter also from bout 1100 to 2300rpm then boost realy kicks in and seems ok. but mine is intermited and wont throw a code. sound bout the same to yours?

[black974door]

oo but mine did it befor the chip install but was very hard to tell unless going up a hill. on 100hp setting it brings the stutter out realy badly

sounds like lack of fuel.

Check your fuel filters, lift pump, if not it could be too much demand for a stock and worn HPOP

[Brawnyrebel]

Im leaning towards lack of fuel as well. I need to find a local KY stroker with a pressure gauge and it could possibly be as simple as shimming the fpr, but i dont want to try it and blow the orings off my 201000 mile injectors.

You'll be fine. I had a shimmed fpr on 210,000 mile stock injectors

[black974door]

i just shimmed mine at 200,000 miles and everything was fine

Did shimming the fpr help your stuttering problem black974door?
