What is the ignition timing?

What fuel?

Did you have to run a different accessory drive to get the 2.9 Whipple to fit? Assuming a 5th Gen Camaro kit?

I think the tuner told me 31 degrees total. Edit: I don't know the timing!

Gas was 91 octane. No meth.

I ordered the 2010+ 2.9L Camaro tuner's kit. The Camaro uses the same drive dimensions as our trucks. You have the option of using the Camaro accessories or the truck ones. I use the truck one because I have Hydroboost brakes and modified the pwr steering/alternator bracket so it would rotate slightly towards the driver's side to clear the bypass and dbw TB.

Thanks for the correction. At my age I can't even remember what day it is. LOL This was my first boost motor so I am somewhat on unfamiliar ground.

I would like to add that my visit at Vengeance was a very positive one. The quality of work and the cleanliness of the shop that I saw really shows a high level of professionalism. Mike was awesome on the tune and shared his knowledge freely. I not only drove away with a great tune but also learned much.
