Is my tune bad? Car keeps dying.

[Motorhead350]

I need to inform some of you on my car the past few months. I had my blower removed for a rebuild and to run N/A Zack put a tune in the car to make it work. It worked and when it came time to put the supercharger back on my tune for the blower was lost.

Later we got something together and it was fine, but I still had a few issues. Keep in mind Zack doesn't dyno tune. When I went to our most recent Marauder event my car was tuned back to stock with the blower on it. :eek: Yes it worked for driving like an old lady and that's all I needed to get home.

A few weeks later I went to have the car dyno tuned and it was set to run with only 7psi because I still had an oil leak from the blower. After that tune the car would die everyday. When it happens is when I am going slow or slowing down. When I let off the gas and hit the brake that's when it usually dies. Backing up into a parking space it dies too.

I know the car needs another dyno tune especially if I'm going to up the boost to 11psi, but could it be something else?

The car was fine before the blower had to come off and we started messing with tunes, but I have no idea if it's simply the tune or there is more to it.

Let me know what you think.

You sure you ain't got a big vacuum leak somewhere Dom? Recheck your hoses and connections.

It's not the dyno tune, that's mostly for WOT settings. It's the drivability tune, and if you have a tuner that only does a dyno tune instead of a dyno tune then a street/drivability tune you don't have a good tuner.

Tuner being the device or the person?

Dom, you just need to get your Marauder to a local, reputable tuner.

I had the same problem with Bob's tune. Change the "rpm in drive" to 800. That's what i did and haven't had that problem since.
