Big cams are tough to tune for sure.

You are going to give up some street manners on the low end with larger cams. Did you change injectors and if the injectors were changed, were they scaled properly. Was the short pulse rate scaled for the new cam size even with the stock injectors? If you didn’t, you have the injectors squirting at a cycle rate for the stock cam which is slightly early for a big cam. When guys tell me "the car smells rich when im sitting at a light", that's the first place I look after I ask them if they have cats on or not.

If your car is lugging at 1300 RPMs in first gear, it's doing in 6th gear, your just not feeling it as much. You can switch to higher gears and that just either gets your RPMs out of the problem area, or raises the problem area.

There are several strategies a tuner can apply to reduce the amount of lugging, but some cams arent going to have stock street manners. www.TampaTuning.com
