So the brake boost is recommended for T-Ing in the vacuum system. As far as the spark plugs what should the gap look like? I just put in stage colder plugs and gapped to 33-34 and was running good with nitrous and when I took the nitrous off. My tuner stated that gap is still ok, but wanted opinions

Sorry pal I just saw this... Yes it's the line you pointed to, the booster line.

For lighting I'd read this pal... Great info and it saves me typing it all! Lol. Its where I learned from years ago and I kept it as a reference just in case.

Plugs you should absolutely gap to 035... They all should be consistent as even a slight variation (or less than 035) can make a difference to the burn and make it a bear to tune.

All vacuum lines are be rerouted to the brake boost. Now question, I have next to no room to put an air filter on the blower it literally sits right behind the drivers headlight. I have searched, searched.....& searched some more.... can you throw me some info on what I can use?? There literally might be 3 inches of width (being gernerius)

If it's a reverse routed blower then you will need a pancake air filter... I use one from AutoZone... Crap brand but it's actually really stout and has good surface area...

Take a look at this... Its like mine. As I said, not a great brand but I change them every other oil change anyway and I have had no collapses... I also know a guy running 16psi on it and it hasn't been sucked in yet so I feel safe at 7.5psi! Lol

Spark plug gap.....??? I am running very rough at idle and getting up to cruising speed then it pans out decent. My tuner said my data log showed pas side bank 2 dumping much more fuel. He said look for vacuum & exhaust leaks or replace the o2 sensor. I replaced all the vacuum lines and sprayed TB cleaner on everything and never heard the engine idle higher. I don't see my o2 sensor randomly going bad and I would hear if I had an exhaust leak.... I believed I gapped my plugs around 35 and they are a stage colder but could I be experiencing "blow out" as the red flags for it appear to be what I am experiencing.

Post #53 .... gap them at .035... looks like you have, but check them again and move on as that's where you will need to be. Make sure none are cracked while you are in there...

Everywhere you tapped a vacuum line you have checked right? Is it rough on acceleration out of boost?
