[QUOTE="euroford, post: 1558351, member: 17667"] I'm out here in CO and drive my truck extensively in the mountains, loaded and unloaded. Properly done, these things will fly up and over Vail pass. I'm running 250/100 injectors and a KC300x for my E99 with numerous supporting mods. My tuning was done by Dave back when he was still with Swamps, i pulled several datalogs for drives over Vail and Berthoud passes and for 1/4 mile runs at bandimere, he revised the tuning several times and I feel like its dialed. I really only run either the "hot street" for all of my driving and the race tune for the occasional fun pull. EGT's are really well managed so I have no reason to run the lower power tunes. I can sustain high speeds and 35psi over Vail pass, the EGTS pretty much hit a wall at about 1200 and climb no further. I do also run a wastegate and a turbosmart boost controller. I think this helps, but is not something that has caught on. So, good parts, good tuning and your good to go. As mentioned above, you do need to keep your RPM's up to keep the turbo lit in thin air. I think slightly easier for me as i'm a three pedal truck. [/QUOTE]
