Is it safe to run my 42# injectors on my car without a tune. I dont have anything done to it but the 42s and i need to be somewhere tomorrow morning and wont have the tune till later on that day. I put my 42s on tonight and pully will be on in the morning but i mightneed to go somewhere first. Anyone know?

 

so are you on the stage 2 tune? don't beat on the car and you will be fine.

 

No im not on anything i just have my injectors in. i dont plan on it.

 

as long as you stay part throttle your fine

 

Alright thanks man!!!

 

why don't you just keep the stock ones in untill everything else is installed?

 

threre already in and i didnt think i would have to go anywhere. Im still not sure that i do i just want to make sure i can get there if needed.

 

When I installed my stage kit i installed the 42's and dove to the dealer for the flash.....I was surprised when i started my car.... it idled like normal , and ran perfect all the way to the dealer . I didn't have the pulley on thou , i waited until after the flash to install that.

 

42's aren't that different from stock. So you will probably still move and run I would just take the time and switch them back to stock if your not going to have a tune.

 

Yeah, shoul dbe OK as long as it isn't many miles. Overfuleing can result in washing down the cylinders with fuel and damaging the rings if you drive too long like that, but I think you'll be OK.

 

youll be fine just baby it

 

Im done with it it did work once i figured out my cylender 3 plug came undone. thought i installed a massive cam. lol. But the pullys on too and the car feels great.

 

stay out of boost. you need to stay out of PE so the O2 sensor will compensate and run you at stoich.

 

I believe GM even said it's ok to drive the car to the dealer to get the stage1/2 tune after and install on the stock PCM as long as you aren't hot rodding.

 

Yeah i drove it and it ran great. I didnt go over 50% throttle and had no problems.
