After installing my sts kit it was obvious that i needed valve springs so Allen "detuned" my truck so i wouldn't tear it up til I got the springs in. Believe me when I say this was the longest 3 weeks of my life. $4000 worth of power and unable to use it. You could imagine the frustration. Got my new tune to go along with the springs and WOW. It took a few days for the computer to "learn" the boost, but now it's a blast to drive. I can now say that the turbo is definately worth the $$$. Thanks to Billy @ TRT and Allen Nelson.
Of course, now I can't stop. I want more. Ordered 2600 stall along with camshaft. E fans are next. I WILL be on the fast truck list.
