with mods in sig would it hurt my car to run 104's in it??? My pcm is locked and can't be tuned so I need to get another pcm.. To tune the car with. But before I installed the 104's I have a ported front mani that would be going on while installing the 104's would it help or hurt my L36 with the 104's my tuner said to run them to help fight kr sesne he can't get into my pcm.

Why are you asking us remember you are the expert on these cars



A N/A shouldn't run AL 104's they are for boosted App. I believe you need a AL605 don't quote me on that Someone with a n/a setup would be better to answer

_________________

i know but i remember a while back i called zzp and they said run the 104's but remember the key here is my pcm's lock and at wot when scanning its seeing 6* or kr at wot shifts. under normal driving is not knocking.

Then are you doubting God's word????

No I just want to make sure its not gonna hurt the engine is all. These plugs have under 1k miles on them.

it shouldn't hurt your engine just your gas mileage

_________________

thats a given but the car naturally runs hot and i am in florida and its still in the 90's here during the day.. But will I lose any power or gain a tick or two?? I was under the impression that if you drop the cc temps that it will make more power..

You have these you shouldnt need anything else.

What is ur gap on your plugs now? Dropping plugs will not get rid of 6* of KR

.055 to .058

Im running .042 on 104's just cause of e85

ahh the smaller gap the closer the spark and the more chance of a little hotter flame..

But i'll have what it takes done to the car to move the air in and out so it shouldn't be to much of a loss to power and what not to the engine. and I also BEAT THE DO SHIT OUT OF THE engine half the time.

605's

you need back pressure in an n/a motor or you'll loose torque and acceleration

_________________

the 104s were free and are almost brand new and i need plugs like asap so All i can do i try them and see how the car acts.. It might love them or it might hate them.

104s are for boosted engines...stick with 605s.
It's not gunna hurt your engine, it's just gunna do nothing but hurt your gas mileage.

How many alternators do you have?

Hmm, that's odd. Glad to hear they worked out. Just take them out of your signature to avoid bashing. lol.

How much of a mileage increase did you see, how was it measured, and over how many tanks? Also, why the mid grade? I'm almost wondering if you could go regular to compensate for the plugs being too cold.

Hell, if it works, it works. It's a subtle change anyway. Even if it hurts a little, it likely won't be noticeable.

quicker respone milage went from low 20's mixed driving to high 20's real low 30's that was with me and my lead foot but the car is hot natured and its still hot as kcuf here in florida. I'll pull one plug this weekend to see how they look and post back.

Yeah ok, I laugh at that one. Low 20's to high 20 to low 30's just replacing plugs?

Proof or it did not happen.

Though, more suspicious is that it went up, when you know he's probably driving harder trying to test out the plugs. Placebo effect works great for power mods, but I'm not so sure about fuel economy. Unless he's subconsciously driving more lightly.

Hell, like I said. If it works, it works.

It does like i said before i'll pull one and see what it looks like and post back with the info
