Just got my A/F with 75 Shot !!!
Well i just installed my A/F Gauge and did a couple of runs but with about 800psi bottle pressure just cant get it any higher in this cold weather. So i thought i should run rich since i have less bottle pressure and usually tuners will tune for about 900-950 bottle pressure, not sure just assuming. I was at about 13.2-13.4 at about 5000rpms and just let off at that. From 3500-4800rpms i was getting anywere from 13.2-14.0 a/f then when i hit about 5k i paused looked real quick and let off and it read 13.2 a/f but again it was 13.2-14.0 from 3500-5000rpms. This was on 800psi bottle pressure and on 75 shot. Does this sound way too lean, especially with that low of a bottle pressure?

I do agree, i did a small vid i know the quality is definitly not there but i did the best i could. On one of the runs i had the bottle closed and turned the switch on to the nitrous so it activates the nitrous tune and i could tell that the tune was definitly kicking in meaning it seemed like it was running rich and timing was pulled because it didnt pull good at all which is expected since its a nitrous tune but im thinking it needs way more fuel and told my friend the same thing if it was N/A at that A/F i would be worried so on nitrous im shocked nothing serious has happened. This vid is with 800psi bottle pressure at 75 shot ill post it once i get it on the pc.

its a dry 75 shot, i have a tune when you flip the switch on for the nitrous it will switch to a nitrous tune. I know the tune works for nitrous because with my nitrous bottle closed and the switch on to the nitrous the car runs like crap too much fuel and timing pulled doesnt pull well at all. I think i need to send it back out to have him add more fuel if that doesnt work then my injectors are maxed out i think.

One pic ive circled the hole and the other i have not just in case.
This pic is also how the hole is oriented in regards of the MAF. I think its fairly even since the MAF angles downward but probably can go a tad higher. I was told that i may also get a lean condition due to the fact that its not facing the right direction or orientation. I think even if its a tad off it shouldnt read 13.2-14 at 800psi bottle pressure with just a 75 shot but again once the bottle pressure hits 900-950 it hits hard and pulls very well and experimented with the orientation of the hole and thats the best as far as i can get it, plus it will more then likely run even leaner at 900-950psi as well. My tuner suggested to me that i should do something with the nitrous solenoid which indicates to me he thought this was a WET system and maybe tuned it for a wet system and not a dry.

I had some ford svo 32's should've kept them. Ill see what frost can do with the tune im thinking he thought it was a wet system and hardly added any fuel compared to running dry. If it doesnt work ill be upgrading the injectors.
