I just picked up a Whipple blower on e-bay for my 2005 Yukon Denali, but it did not come with electronics. Can I use KB's newly released piggy back replacement? Or should I go with a Wester's tune of the stock ECU? and just add larger injectors?

What can I expect in terms of power increase? Can I expect 450 hp? I am supposed to have 335 stock... (The Yukon has the 6.0L Vortec engine)

I used to drive a F-150 Harley truck with a Intercooled Eaton M112, which I changed pulleys to provide roughly 10PSI (always Sunoco94 octane, and Michigan wheather), without any tendency for detonation, or pinging. However, I was lacking a little bit top end on the Roots blower, which I hope the screw will give. Hence my decision not to go with a Magnusson/Radix or similar. What is a safe boost range with the 6.0L on the Whipple, without Intercooler? No racing, just "normal" driving. I think the Whipple is sittinga t 6-7 PSI stock boost. Can I go up to 8-9 or is that pushing it too far without an intercooler?

Thanks in advance,

Anders

PS I will install myself, but if I change my mind, anyone know any good installers in Michigan?

 

You will be better off with a tune and larger injectors. There are lots of people with whipples that get rid of the whipple craptronics to do that anyway.

what is kb piggyback electronics

 

The KB piggyback electronics is a glorified word for a tune. Make sure that you install the 42lb injectors and get a csutom tune. On a 6.0L you should be able to put down 400Rwhp easy. 6lbs is safe w/o intercooler.

 

400rwhp easily. I would just tune the stock pcm and get larger injectors. Piggybacks are kind of a pain.
