leave the fuel pressure where it is...you got it set to where the numbers look good

If the pressure is dropping under boost, then you probably have  a fuel supply problem and I don't think the hot wire is going to fix that problem.  Make sure the fuel filter is new (I think you changed that recently) and install a hot wire...if still low, then that pump that the guy put in would appear to be going out.

Did you check the pressure under boost with the gauge I loaned you?

Yes, the fuel filter has been changed.  I've NEVER checked the fuel pump, so maybe i can drop the tank and see what's in there?  I havent had a fuel pump installed on the car since I've had it.  Only thing that's been changed is the fuel tank within itself.  I didn't use your gauge to check while driving b/c the line was a little too short.

I dont think a stock fuel pump would last this long, so I have to assume it's aftermarket.  then again, it could still be in there.      we'll see though

would this be an ideal pump to buy when i get one?

[SuperSix]

That's a fine choice.

Includes a very nice hotwire harness.

I already have the hotwire kit!  Thanks Supersix

Im purchasing the TT chip and 42lb injectors on Monday.  Should this purchase help me with the issues I'm having?  I lowered the FP to about 42 lbs static, changed translator setting to lean out at WOT about 10%, and when I floor it for about 3-5 seconds my O2's show something like 850 and the KR about 6.7 last I checked.  I don't beat on the car.  I only floor it when tuning like I've been trying to do for the last three weeks.  My question is, is the stock chip's timing that high?  Shouldn't I be able to drive the car regularly now that I've done the basic upgrades?  The car pulls great at part throttle, but I can def tell when the KR kicks in that the car slows up.  Thanks

When one gets that rich, one often sees timing retard in my experience.  It may not be related to the timing, or it may be.  It may be rich detonation, or a phenomenon that looks like detonation but is caused by too much fuel in the chamber which will not burn cleanly.

The TT chip will not cure mechanical or electrical problems with the car.  On a car that is running properly, it will allow you to run more boost due to its lower timing and thus make more power.  Overall drivability will increase as well. It will allow you to shape the fueling curve if required to keep the wide open throttle below 800 where it belongs.

the new injectors should spray more evenly and make for a better run.

Thanks. As mentioned before, I've definitely seen a huge diff in the car after installing a healthy fuel pump and hotwire kit. My problems arent what they were before. But for the base FP to be set where it should be set at, it worries me that the car is still not running up to par in stock form. I honestly don't know where else to go from this point. My goal was to be able to go WOT all day long in stock form before any mods or upgrades. I feel like I'm coming up short.  Thanks again for the response.  I'll keep searching until I find something else to fix.

been trying to get you to put in a decent chip and injectors for a long time

That will give you know quantities that can be adjusted

Yes you have sir. I can def admit that.  OK, so after the install, then I can come back and give you guys some numbers.  I went to gnttype.org for instructions on how to remove the injectors.  Seems intimidating.

[Steve Wood]

dead simple...parti cularly since they have been out recently

What intimidated you?

[Steve Wood]

BTW, contrary to the instructions, I always leave the regulator bolted up to the rail so that it comes off when the rail comes off....just disconnect the fuel return line from the bottom of the regulator

[daveismissing]

a data point: 93 octane, stock chip and injectors- I don't see any retard.

I dont remember exactly Steve.  I think at the time i was reading it, i was rushed and wasn't paying attention.  Just read it again and you're right. I would prefer to leave the FP regulator on there so thats good news. Thanks.
