so there are 2 things i have questions about that strike my concern. the guy who looked at my car who replaced the tcm told me i have to get all the electrical **** out of the bcm (fuse box) in the fusebox i have my wideband gauge and my radar wires with fusetaps in fuse slots so they turn on and off with the car.
is this safe? or is it not safe?
also i had my custom led tails a member here made for me. they were wired by taping into the tail light harness for them to function. the guy removed all the wiring and has it set back to how the car comes stock because he had a problem with the brake switch circuit (happened bc the bcm was fucked up and not because of the tail lights) i ran my custom tail lights for about a year wayyyy before any of this problem happened.
is having my tails hooked up by tapping into the turn/brake and running and ground wires safe?
because im wondering if i should re hook this stuff up when i get my car back
any input can help

If you have these kind of fuse taps
Throw them out and get the add a circuit.
The first kind either give you an unfused wire or makes the two circuits share a fuse depending on which way they are inserted. With either kind you still have to worry about drawing too much power through the fuse block and burning up wires or the bcm. While you are probably ok with the two things you have wired up I would try to find an unused spot if at all possible.

I wouldn't hook any wiring up until all your problems have been fixed for a while.

dealer replaced the bcm and the engine harness. reprogramed bcm and it reprogramed the pcm as well putting the car to the stock tune.
guy who supercharged and tuned the car went to gm and reflashed the car with the HP tune.. it wouldnt start and so he told the tech to check the plugs. they were shot said the tech. so the tech replaced them, car started up. idled fine. and it ofcourse did the same thing which woukd stall out after driving it. a little bit.
so this has to be a tune issue. so the guy who tuned it said tow it to his shop and he'l look at and go through the tune top to bottom. since everything else has been replaced/eliminated for problems.
I wish there was a tuner who was on here and was local that could just tune the car and itd be done quick!

I would talk to Fred Jr. @ SMG Automotive in Hopedale MA he is an expert on the delta body (has a straight up cavalier drag car) and tuned my car to utter perfection which has had no problems for almost 4 years now. Good luck.

Dealers have HPT? Wut?
Sounds like you have a mechanical issue IMO. If the ECU was flashed to stock and the the wiring harness was replaced i don't think it's tune related.

no clue havent tried it because you cant bolt it to the supercharger . its at the shop who did the sc install im bringing them my stock injectors tomorrow and telling them to put them in the car and scale them to stock and see if the car stalls out. because thats what the one guy who replaced the tcm said because he said he was getting little to no power from the injectors when he was testing them, they were not scalled right from the start.
what brand they are i have no clue. zzp just put them in their injector box and sent them when i upgraded to stage 2. there 60# thats all i know and all zzp knows because calls to zzp were made asking what kind they were and they said they didnt know.

reallly hoping my 60's in the car are my problem because they may be dead. because if the injectors are NOT the problem than i legit don't know.
because the pcm,bcm,tcm and engine harness(one on the car prior had shorts in it) have all been replaced and im still having problems.
unless this shop legitly doesn't know how to tune a damn 2.2 supercharged cobalt.
because the other guy i took it to told me that few things in the tune weren't done the way he would have done it.
one being the injectors weren't scaled properly so maby them not being scaled properly from the start fried them?
anyone who can give me some knowledge or help i will greatly appreciate it

because the guy who replaced my tcm (his name is anthony) said that he was getting little to no reading from those 60# injectors that are in the car now. so he suggested i put the stock injectors in the car, scale them to stock specs, and try to see if the car stalls out if you drive it. (yes i know it will run like **** and run rich), but it would be a way to test to see if the injectors are my problem, because he said if they are the problem he will get me a set of 42#
