it doesnt help that my installer(chevy dealer with a performance shop but no dyno) is about 35 miles north of me and the tuner that they recommended is 45 miles south of me. hard to troubleshoot if its tuning issue or mechanical issuse with the large distance. the tuner said the MAF has excellent readings according to his log(data sheet). all the plug wires look clean and seated properly. if the tuner cant get it straight i will have the stock throttle body put back on to see if the VMAX is the culprit.

Keep us posted!

Also, I'm running the factory spark plugs. Could this be an issue? Is there certain aftermarket plugs I should be using?

Stock plugs are fine. I have had this cam for over two years and the tune is most important in getting it to run good. Understand that it will never drive like stock at low rpms in low gear, but it should cruise fine in high gears at highway speeds. If you can't find a tuner near you who can get a handle on it, you may want to get a mail order tune from a tuner who has experience with this cam. There needs to be street driving tuning as well as dyno tuning to get it dialed in. A future mod you will find goes great with the G6X3 is gears, 4.10's or 4.11's.

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
