Thanks for all the positive feedback/comments doods! Been incredibly busy since the install so I have yet to write a follow-up on the install (issues ran into etc etc) for this thread... However I will say it's damn nice to hear that familiar whine again, truck pulls, accelerates, and hauls much butt ultra smoothly... Surprisingly smooth... I love it.
Come spring I'll be looking to pulley down (9ish lbs), pin the crank, add an HD Tensioner, corsa exhaust with escalade bumper, and black bear mail tune or livernois dyno tune... Would really like the tune to incorporate the tow haul button for a more aggressive track style tune and when off, a nice safe, fun and solid daily driver tune...
The goal is to be rocking a set of ck375s with new rubber before I pull the trigger on that stuff... And before all that, a Lotta saving up!

Thanks again guys!

Everytime I come on here someone is slapping a supercharger on their Denali and I want one so bad....lol

So how's it drive? Does it wake up the beast? The 6.2 rips stock, I'm m interested in what you think of it blown!

 

[FamilyTruckster]

Drive is incredibly smooth, the power comes on strong but smooth... +150 horse will wake up any beast lol! Definitely more advanced and evolved than my previous MP112 on my LQ9, loads of fun. Just wish the roads were less covered in snow and ice right now...

So if you don't mind me asking what do you have $$ into the FI swap?

Throttle response better? Can it smoke all 4 tires? Does it kill fuel economy or towing?

- Just under $3,000 total investment (I purchased the blower used - and "rebuilt" it myself).
- Throttle response is better i suppose, never really noticed much of a lag or poor response prior though...
- still only spin/squak-s left front and right rear (however I have yet to romp around with trac ctrl turned off... tons of snow since i finished the install)
- fuel exonomy has not changed what so ever (still commute 40 miles to work daily with no extra suck)
- never towed and no plans for towing.... though if you check out SmokyMance's write ups he tows often with a magnuson blown 08ish denali with no issues that i am aware of

Bottom line, from the two mag blown late model GM trucks i've owned and experienced thus far... you wont regret a thing...

Now it's gonna be me asking you for a motivational ride, lol I'm still waiting on injectors

 

[FamilyTruckster]

Anytime!
Tonight I hope to find some time to carve out so I can wire up the 3.5 bar MAP sensor for my interceptor gauge and clean up some of the wiring under the hood... Finally was able to warsh some of the snow off...
