The stock injectors work fine to test if it will start and idle. Flash back to stock tune and just stay out of boost. Many have driven to the dealer with a stage 2 pulley on and stock injectors, installing the injectors at the dealer and having the stage2 tune put on.

Oops just remembered you werent a stock SC. Don't put your stock tune back on.
You can put in the stock injectors, rescale em and see if there was a problem With the 60's. Your problem is if he couldn't scale the 60's in the first place why would you think he would do any better with the stock ones? If it doesn't work you still won't know if it is a bad tune or an issue with something else.

I had someone come by my shop in December and he had a dead 50lb injector. Injectors going bad right out of the box is not uncommon. I bet they were checked from the factory but that doesn't mean by the time they got to the vehicle, something hasn't happened to them during shipping. Let me know Brandon I want to see this car running.

Also you on New England Cobalts facebook?
Whaaaaa? I've been off the forum for like 3 years since I did everything to my car and finally graduated college and have been playing with it again. Last time I was there was around 2009 I guess. But I wouldn't trust anyone with a delta tune more than Fred Jr.

Also I can't stand Fb and rarely use it so I doubt it I was in like "Chevy Cobalt owners" group back when Fb was new... in like 07

What happened to fred? I really hope his shop in hopedale is still going strong...

yeah im hoping the problem is the injectors because if it is im going to get 42# and i think have this other guy scale them because he already is a much more knowledgable guy and all that.
said there was a bunch of things that werent tuned right/the way he would have tuned it.
and yeeah i just want the car back already and running order. this is crazy

yeah who knows. ill find out. the place where the car is at now claims its not the tune altho i call BS because theres nothing else electrical that could cause a problem.

PCM,BCM, TCM AND the whole engine harness has been replaced.

Ya Fred took someone to the cleaners on their car and then demanded more money. He told the guy that he sent out the head and block to get worked on in februray 2011 but when the guy approached the shops in August, they hadn't received anything from Fred. Car ended up getting traded in because after 13k in parts and "Labor", the car was burning through a quart of antifreeze a week.

I wouldn't trust that guy to put a cap on a soda. He used to be good from what I've heard but that was over 4-5 years ago. Now his tunes are extremely outdated and work ethics are in the garbage.



Brandon, I'm glad you found someone up there to get you squared away. When you came to the shop there was a few things john was going to fix on that tune. If you get the car up and running correctly and the guy tries to dial everything in but can't just let us know and we can look over the file just like before.

well kevin has had the car for about 2 weeks and has made zero progress.
i dont even know if there working on it or if it is just sitting in the corner of his shop.
he is very poor with communication. my dad went there today to drop off stock injectors and no one was there.
so tomorrow is another day.
but this other guy whos 40 mins away who looked at the car seems like he would tune it ALOT better than kevin did. my plan was to get my car back from kevin than go up and get everything relooked over and tuned how this guy feels it should be done.
but i cant even get to that step yet.

Just keeps turning into a bigger nightmare by the looks of things. Let me know how it goes. Hopefully Kevin will get his act together and finish the car.

update: just got off the phone with my dad, he went to the shop today to give the guy my injectors. he said that he put different ones in there and the car ran great and he took it out and drove it for a few miles no problems at all. and said he just had to fine a signal to somethin(exactly what i dont know because i didnt talk to the guy) but he said he was making alot of progress
so im pretty sure my injectors were messed up because there was little to no power downlow
so hopefully the guy will find this "signal" so my dad says and ill get my car back real soon

it would


edit: well actually they could have just had very poorly matched flow rates of the 4 injectors from the factory
