Need a drivability tune on my car, any experienced tuners do this?
I had heads/cam/tune done at a shop but my car bucks insanely at 2k rpms and below. If anyone can help me out and get this car running good on the street, please send me a PM. thanks

However, if they couldn't get it right on the first try I wouldn't give them a second chance. Pick up a copy of HPTuners, a wideband, and learn it for your self.
I know that's not what you wanted to hear but the fact is that no one can ever tune a car as good as you can.No one drives it all the time and can make the small changes necessary. Good luck

I'm scared if I try tuning myself, I will screw up my car though. It seems like a lot to learn and i don't even know where to start.
The shop said they couldn't get the bucking any better, i already talked to them.
Patrick G was saying it could almost be eliminated if someone spent a day with the car logging and tuning.
I guess I could get the HP Tuners or EFI Live but how do you learn how to use it?

Thats what big cams do, they buck. I don't see how you could tune it out.
I could be wrong, but I've never seen it not buck, unless your idle was around 1000rpm's and/or the cam was on a 114lsa or more.
Peace,
Craig.

I'm not saying it was a bad tune or anything. Shops don't have time to drive around a car all day adjusting things. I'm just saying I've heard if you spend a lot of time playing with the tune, you can almost eliminate it.
I'm just wondering if it can really be fixed or if I should put in a smaller cam.

Edit: this was my head cam motor, the 408 was tuned by G-force from the start.

Jimmypop...your cam isn't THAT big~ it's on the larger side but you shouldn't have ANY problems after a half decent tune.
i suggest you stay away from HPE tuning??(referring to post 7 and a personal friends account of their tuning)
and yes, tuning it yourself can be risky if you don't know what you're doing....

I am going through this on my 408. I drilled out the hole in the throttle body (start in 1 /32 increments) until my IAC position got down to around 80 deg. (It was as high as 170). You need tuning software to do this. Then let it idle until the STIT's find they're way back down to a reasonable level. It idles great now. And this is a 249/244 cammed 408. Don't let anyone tell you its normal, it is not and can be fixed.
+1 for taking it to G-force. I know for a fact that Mike knows how to do this. Heck, if he can get a 255/250 cam to idle...
