My MBH longtube headers and catless mods are almost installed. Unfortunately though it doesn't look like I can get the header matched tune today.

My question to you guys is this: since I'm currently running the stock, untuned ecu, am I safe driving home from San Diego to Los Angeles this way? I know my check engine light will be on, but I want to make sure I'm not doing any longterm damage to my motor if I only drive at partial throttle. The tune will be installed in the next couple days, so just making sure that conservative driving in the meantime won't harm anything.

Please lete know asap!!!

Thanks!

Just don't beat on it and you will be good for the time being!

Congrats on a great header choice!

I would not drive it.. Not for another reason then the initial drive should be all or nothing meaning.. I would want to jump in and beat the snot out of it feel the new power here the new sounds.... All at once!

Your fine, just don't beat on it until you get the tune.

How do the headers sound?
