I am new to the site. I have a 91' rs camaro 5 spd with a 305 TBI. I just got my new hypertech power chip in today. After i installed it the injectors arent putting out any fuel, i swapped it back with the stock chip and everything worked fine again. I tried putting new chip in again and no fuel out of injectors. Anyone know why? I am positive that this is the right chip also. Hypertech 121372

 

That's why you do it yourself

 

I got ahold of hypertech today. Turns out they dont make a performance chip for the computer i have. Go figure what great luck i have

 

Like I said do it yourself, it really pays to learn. The money
you spent would have helped yo pay for the equipment
you would need.
Read the stickies on the top of the DIY and see what you think

 

Gotta be a VATS issue.

 

Hypertech doesnt even know their own products? What a joke. I wonder what they call this, then:

A whole boatload of chips for TBI engines in Camaros and Firebirds.

 

the one thats was for my specific vehicle was the 121372 chip

If your chip that you currently have has the 4 letter code : ANTR hypertech does not make a chip that crosses. I did however get ahold of jet chip and they copy your stock chip and then send you a new performance chip
