Just got my car tuned at church and put some beafy 550 injectors on my stock ls with a slap on turbo. Now with the new injectors my car sputters and struggles to start with the rpm's fighting to get going. But after that they seem fine.

Im thinking the injectors need to be cleaned and tested since they were used, but i'd like some more opinions before i spend the money and downtime sending them off.

Any other possible things to look at? i was thinkin of taking back to church to take a look at the tuning of the injectors, since church got some guy working for him to tune it, i can never be to sure how the job was.

 

Probably something with a start up fuel multiplier or something of the sort. Give them a call and see what they say.

 

either its just my luck or this guy is extremely hard to get a hold of, hes a busy guy. thats why i wanna check with u HT'ers before i try giving him a call again, ttt
