I have a 95 with dsm link v2 I had a crack exhuast manifold. And now I'm running worse Sence I welded it what happened

Depending on the size of the crack in the mani, you could have altered the way the exhaust flowed out of it, causing more pressure in it... also could have welded to much inside causing some exhaust distortion...

Did you un hook the battery? That would of re-set the ecu and erased the tune. Also if you welded the manifold on the car than the current could of also damaged something in the electronic system.

it wasnt fully tuned still had the top end to finish but couldnt due to bl's and a air intake so i got them fixed then noticed this crack and thats what i thought was that it needs to be retuned again for the pressure crack was about 5 inchs around right at the turbo flange. and now its running alot worse will barely even run at cruise speeds only runns somewhat right in boost, 10 pounds due to the top end tune not being there will be 15 when the tune is finished
