What does "safe tune" mean?

[shanec]

In looking to get blown, I want to stay safe. I talk to people about 400-420rwhp and they think I'm silly. "The tune matters a lot more than rwhp", they say. They say, "just get a conservative tune and enjoy 490rwhp" or some such.

What's a "conservative tune" or a "safe tune" - and how do you know the shop you are working with is going to give that to you?

A "safe" tune usually means a little timing and a lot of fuel. Basically doing as much as possible regardless of the PSI involved to assure that there will not be a failure due to detonation. Now that doesn't mean there won't be a failure, just that as much as possible has been done to avoid said failure due to the tune.

A wise tuner once said "there is NO safe tune,when you beigin to mod"
That is pretty true.There are safer tunes but still no gaurantee.And running too rich can't hurt just like to lean.

+1, I agree 100%.

I definetly wouldn't consider pushing extra PSI as being safe.. seems like everytime I hear someone snaping a rod on a stock engine they are running a safe tune with over 10psi.. From multiple reports and other's frist hand experience, keep your boost at no more than 10psi and you should be safe with a good tune.

Zactly - I will only add that there is some debate over how much fuel is the 'safe' word attached to.

IMHO once ur 420-430+ whp there is no "safe" you must be prepared, both mentally and financially, to replace your short block

good tuners make the tune as "Safe" as possible unless you ask for a more aggressive tune.

I was kind of assuming that. With Roush & Saleen selling cars on dealer lots with full warranties and 400rwhp on GT blocks & clutches, I figure that must be a really safe number. Also the aftermarket superchargers with factor warranty resumptions all carry about 400rhwp. All that's gotta say something. Would only assume a bit beyond that would fade into not-so-safe.

Never a truer statement made...

Chad, do you have a dyno chart for your car? I'd like to see it. And what kind of mpg do you get?

Help me out on timing numbers. If somebody says their car has "only 14.5 degrees of timing" - he stock, a little more aggressive than stock, what? What number would be aggressive (heck, what number would be stock)?
