X2 Forecfed is using the correct method for tuning. Please don't throw 28-36* at this thing. Nothing is more irritating than pulling down a fresh build for a rebuild/replacement. Ask me how I know. And it wasn't timing in my case. Just a leak. Love the truck and look forward to your first 5 second pass!

The fuel you run will have a large effect.The way I tune would prove what the engine wants. Simply dial timing back to some thing ridiculously safe like 8*. Get your AFR squared away and ramp up to your desired boost level watching plugs. Then add 1-2* until you stop making noticeable gains MPH or your plugs tell you you are too hot. Make nice easy consistent launches and watch MPH ignoring ET until you get it dialed in.
Tuning that way is always safe and if the engine wants 28* then it will be clearly seen in the MPH/plugs. (chances are it won't)

Another newbie question, What is the limits of the stock l33 camshaft? It seems about 5400 rpm for about 3 seconds it somewhat stops pulling or just tapers off noticeably. I have a tick stage 2 turbo cam but was wanting to see what we could do with the stock cam. I know I really need to get this data logged to know what exactly is going on. It may be fuel but was wondering about the cam. Thanks Mark
