I should rename this the misinformation thread.......
In a nut shell you want to out do an LBZ but have no idea what modifications are done to the truck but he gets by you on top end. Eric's Extreme tune should not be ran with the Tow/Haul button engaged (for all purposes it is probably disabled in the tune) and you are milking your injectors..... in easy terms, you ran out of fuel.
Forget any FICM tuning, injectors, filters and spray wax, buy yourself a fuel pressure gauge. Fuel first, then modifications. And another thing, nobody can tune an engine to its full potential unless they are sitting in the passenger seat with a laptop. Email tunes are generic. I won't even address the key a ma thingy.....
If you have deep pockets I know a Canadian that can set you up with a twin turbo.

Tire speed rating dictates the original manufacturer setting of the speed limit on any vehicle. Custom programming removes the limit. I milked my injectors down to zero fuel pressure in the 1/4 mile, hence no top end speed. New pump, fuel pressure, top end speed increased. Pretty simple.

This can get addicting...

So yesterday I got the new intake and the php tuner. The intake largely seems to do nothing as far as feel. But it must be delivering cooler air, just by design. I really can't tell without any technical data though.
The FICM programming has made a noticeable difference in throttle response. I also tried something with my sct that has really helped turbo spool. I set my running idle rpm from the stock 625 rpms to 725 rpms. It keeps the truck above 700 rpms at all times and makes almost instant boost. Whether Im sitting at a light or coasting down an exit ramp, as soon as I hit the pedal I have boost.
Still researching options for fuel delivery and monitoring.
