HP Guestimate

I just purchased a 2010 Inferno Orange SS/RS, it has 10,100 miles on it. the previous owner drove it 2K each year. at 5K miles he had the dealer install K&N CAI, JBA Pacesetter 1 3/4" headers and Magnaflow Cat back, He also had it tuned? This is my first LS3 so what do you all think this thing is making for HP? 10HP Increase 20? I have had other performance cars that I have dynod and they all take to bolt ons different.

you should have gained about 40 h.p. if the tune is good and it would have required most likely ignoring a CEL check engine light from delayed response from the O2 front sensors. And doubtful the dealer took to removing torque management or other tweaks to the ECU.....

Couple questions, is yours an auto or manual? Also, is it a dyno tune or a custom tune?

The car goes good so and on my 4th gen (LT1) I spent a lot of time on the dyno. I just have never had an LS3. I know the LS motors take to mods well but in my 4th gen the power was all in cam and heads etc not just bolt ons and tune. I am not looking to modify this car further as it goes good as it is I was just wondering. I doubt I will dyno it but maybe someday!
