SignUp Now!dont want to do to much to it because I will find my self beating the car and breaking something
I am from the same school keep an eye on thing replace what need to be replaced an I don't want to go off the deep end doing all kinds of thing to itGlad you didn't fall into the "replace everything" trap that was beginning to show in this thread.
I've always had good luck over the last 25 years by replacing things as they needed it, not just because someone says I should. I like the old addage, if it aint broke don't fix it.
My 86 is my modded hot rod and it modified accordingly. But..... My 87 is my stocker with extremely mild mods (chip and blue top injectors). It has 135,000+ miles and still runs STRONG! Nothing else has been touched. IOW, original everything else.
If your car is running good with no issues, then leave it as is, if that's your desire. The Commander chip is a good choice for your setuup, the stock chips are just no good for today's gas, etc.
I will add though, A Scanmaster should be very high on your list of next purchases.!!!!
would a new AC delco fuel pump work as a good replacement ?
Check your fuel pressure with a gauge that you can monitor while driving.just purchased Commander chip going to start with that
what about if I keep the stock injector am I going to have a problem with either of the pumps that where mentioned ?
Personally I don't like walbro pumps anymore since they have been counterfeited, I use a company called deatchworks American made 300lph
Fits in exact location and is much quieter due to its impeller design
Most people don't know about the pump but either way you need to do one so So the right one!

Check your fuel pressure with a gauge that you can monitor while driving.
The commander chip is going to need you to raise the base fuel pressure (idle pressure with vacuum line removed from the regulator) up to 43-45 psi. The instructions will specify. In order to do this with the stock regulator,you will need to crush the regulator. A very large pair of adjustable pliers works well for this as you need to do this while the car is running and you're watching a gauge. If you crush it too far,you won't be able to reverse the procedure. The Commander chip is going to raise the boost from stock to 16-17 psi. This will require your pump to perform better than it ever has in its long life so it is crucial that you find out if it is up to the task. If your fuel pressure is 43 psi at an idle with the vacuum line removed from the regulator and your turbo makes 17 psi of boost you had better see 60 psi on the gauge at full song. If you are shy of that number when you check,you can buy a volt booster and a fuel pump hotwire kit. Depending on how far short of the 60 psi you find yourself to be after the test,these two items should get you where you need to be and you won't have to drop the tank and you need these two items anyway. The injectors are likely to be iffy also. If the car doesn't perform well after the Commander and confirmation of adequate fuel supply,we should look at those next. I have some injectors that will work with that chip in case you need some that will save you from buying new injectors which will necessitate another chip.
