I have a 2009 GMC Sierra Denali 6.2L (L92) engine. I have 1 7/8" Long tube headers with 4" single exhaust all the way back. I am wanting to take my stock intake manifold off and send it to Peak Speed Shop and get it ported out and equipped with a 102MM Nick Williams Throttle body. After I do that I am going to need my truck re-tuned to reap the benifits of the larger intake. I live in Alaska and there isnt a reputable tuner anywhere around that i can take my truck to, can anyone help me out and point me in the right direction on how to get this accomplished.

Thanks
