Twin 76 first drive video.
The plan is to have speed inc tune it. I was hoping that the tune that I just got from then would be enough to put 100 miles on it. Does not look like that is going to be the case.
Can anyone tell me if I am good to drive the car 20 miles? If I do not get any where near boost. The fuel pressure is at 3psi and driving I am in the 10.8 to 11.5 range in AFR.

Yeah sorry that was a typo did not even notice that. I did the wd40 test, yeah no leaks. Car did nothing different. Also by lowering the pressure with the car idleing my vac went up. so that is a positive. It is not have the problem that it was with it dying at stop lights.

would wd40 really work? I would think if anything, it would make the rpm's go down cause its not as (flammible) i guess you would say. lol just curious, always up for new ideas. what about this? as far as i understand. efi cars require alot more pressure than a carborated car. if this was a carb car. the plugs are pig rich, it loads up something fierce, and backing off the fuel pressure fixed it but not running the correct amount. i would say to big of jets or to big of a power valve. basically sounds like backing off the fuel pressure is a way of giving the motor less fuel but now the fix. would that be the tune or too big of injectors? or am i looking at this wrong? lol im new to fi so im trying to learn to.

where are the O2's in relation to the downpipe outlet? I know my car isn't FI but if I run my cutouts open for too long which are on the QTP cutout-ORY, the sensors are only a few inches from the outlet and I eventually get an insufficient switching code and it starts running like crap, smelling like raw fuel, and missing, close the cutouts and it goes back to normal after 10-20 miles.
Could be part of the problem if you're still running open DP.
Beautiful set up though!

Fortunately I am running open loop so there is no need for o2's. I did however just find out very important information in regards to my tune that may be causing the problem.
Apparently there was some confusion on the 2 bar/3 bar tune. They put a 3 bar tune on, I have a 2 bar map sensor.... I am going to buy a new sensor as we speak!
