[tomkat69247]

amen to this sticky.

[Hambone691]

So if i have a superchip tuner & have the performance tune in it is it ok to spray it like that ?

[GTRACER88]

Not if the tune has advanced timing on it.

[Hambone691]

It has a 87 tune : 93 tune : stock so I dont know what it got anybody using superchips tuner & spraying ?

[GTRACER88]

Most likely the timing is advanced. If so then the answer is no. You cannot use it. More than likely you can't use it. Im pretty sure its a canned tune for N/A applications.

[Hambone691]

So to spray then i should put it back stock then try the spray its only a 75 shot ? Also whts the best tuner to get to use spray with ?

1. Yes.
2. If its stock tune.. there is no need for a tuner... catch my drift? But for N/A or if your spraying a higher shot people like SCT and Sniper. Check what your local dyno operator uses as his software and get that.

[Hambone691]

Thanks for all your info Man !!!!!!!!! Last question is the stock tune good for up to a 100 shot ?

[GTRACER88]

No problem. Yes.

Anyone know what causes Nitrous Backfires?

What happens on a backfire is the engine goes too lean, and the cylinder becomes very hot and has hot spots glowing. When the intake valve opens, the incoming nitrous, air and fuel mixture is so combustable that it ignites independently of the ignition system, causing the mixture in the intake manifold to be ignited. Now, nitrous backfires happen on both wet and dry kits, but for different contributing causes. Both happen because the cylinder gets lean and pops back. A too low rpm engagement is the most common cause. The reason being that at a low rpm there isn't enough velocity for the fuel and nitrous combo to be carried into the port, so the fuel falls out a little causing a lean condition, and a pop.

So is that why it's a good idea to get it tuned then? I mean as far as making sure that your cars AFR is where it needs to be on all motor before firing the nitrous, and while the nitrous is engaged?

Yes, A/F and timing needs to be right.

Thank you sir

Great write up! So I just love loved how well the eclipse drove after the piston rings were fried and vin diesel sat in the car car great withe no floor board in it lol.

[MadBeau]

Good write up. I hate getting asked stupid questions about my "nos" setup.

[99BLACK HAWK]

thanx a lot bud the write up helped me out a lot 2..
