Good luck on the install, I am also looking into doing the same thing to my 09 Silvy
What kit are you going with? There are some vids on you tube with the install.
I would think that you would need to tune in the MAF, add fuel and watch your timing.

not a kit im building it myself
me and my friends built that kit in the video
only took about 58 hours 3 day weekend
actually still waiting on HPtuners to get back to us on an issue we have, where the PCM commands a 12.2 afr over 12,700 hz or so, waiting for them to support a map OS or something,
we are stuck around 12psi or we go lean
Thats what i was wanting to do also, is to build my own.
Hey denmah, im the one that had subscribed to you on youtube and asked a question about the turbo kit. name is 88coupe50
also, a lot of people are having to upgrade the MAP sensor to a 2bar, have you done that with Corey's truck?
a local corvette builder here were im at put on a sts twin turbo with 5-6 psi on a ZO6 which only dyno'd a little over 600, and installed the 2bar map and was able to tune it better and gained near 40-50 more HP.
here is the ZO6 without the 2bar MAP http://www.youtube.com/watch?v=OQeeAkvvRoQ
still had to work the bugs out, and this was the 1st and 2 pull n new engine http://www.youtube.com/watch?v=UiG9JmAxjus

and what paramaters u guys using on hp tuners to tune with boost on stock injectors?
ditch the maf get a 2.5 bar map sensor crank up the boost and tune SD.
Im in the same boat...you can use BlueCats EQ <> VE program to make a "virtual" VE table using the coefficients, then apply your AFR Error % to that table, then use the program to generate new coefficients to put into your calibration.
Search for Bluecat(sp?) maybe its "Blucat"...Im not sure but the program is called EQ <> VE...check it out!
