Thought i should introduce myself since i have been posting already. Allen resently installed the Trick Inc. turbo system, shift kit, corvette servo, walbro fuel pump, injectors, guage pod, AEM wideband, boost guage, and of couse the turbo itself. The only other modification is the exhaust. When there was the get togther and the trip down to Edinberg the other night the truck ran a 14.3 @ 96 mph without dropping any weight, (tailgate, spare, backseat, passenger), i also was on my everyday 33 inch nitto terra grapplers and 4x4 wheels. So, obviously the potential for this truck at 5psi is really high. This turbo kit is the first of its kind, so Allen and I are learning as we go to a certain extent, but with my limited experience in forced induction the installation and transition into it has been seamless. But, to be honest that is most likely due to Allen's customer service and expertise. I would be happy to answer any questions and can give answers based more in the daily driving and the "seat of the pants" part of the experience rather than tech you to death like Allen would be happy to do. ha ha On a side note; I am the son of a mechanic who owns his shop here in Texas. And in regard to Allens professionalism and willingness to hear and answer to dumbest of questions, as many times as you would like to ask them, it is unheard of to find his equal. You may find a mechanic who can do some of the things that Allen can do, but not all and not as good. And you may find one that would listen to some bullshit questions or has good customer service, but not be able peform to his level. In short, Allen knows what the hell hes doing. Thats why his customers are loyal, and if its not quite right, he always takes the time to make it right. Ok, thats my two cents.
