I think thatās the way to go. If I put a supercharger on mine I would not rely on the tune from the manufacturer. As a matter of a fact I wouldnāt even bother with super or turbocharging anything unless I knew I had someone to custom tune it afterwards.
All I have is a Chevy with a aftermarket turbo kit so itās not like I have a ton of experience supercharging vehicles either. In any case donāt even believe what I say. Just do some research into places that do a lot of hi performance work you will find that all of them have someone who does custom tunes for the vehicles they work on. Itās for a reason.
Whos the tuner?
Petty's Garage is not a new tuner. Petty's was involved in the tune from day one.
i dont know the new in house guy. The consultant came from Roush and has asked not to be identified.
ill be curious to see what the power level is once they have a CARB approved tune on it. Right mow Livernois is only making about 10hp and 20tq more than Edebrockās carb kit despite the bigger blower. Ripp makes more power still, but isnt carb approved either.
Regarding power, I am trying to reconcile the statement on Magnuson's website that says "In stock trim with no other system modifications, this kit provides an AMAZING 440hp AND 380 ft-lbs OF TORQUE at the crank, equivalent to ~372 REAR WHEEL HP." But Livernois says "adding up to 120hp peak gains". So per Mag you get ~440/372 and per Livernois you get ~405/345. I wish I knew what I should realistically expect. The Mag numbers are pretty close to Ripp if in fact you get a full 372 at the wheels with Mag. I am interested in RIPP too but I like the idea of making HP at lower RPM. Not because I think I need more power rock crawling but I just don't love doing 5-6K RPM and I want access to more of the power at lower RPM even though I may give up some power at the higher RPM. Having said that the only time I really need more power is in the sand dunes in 4-high so maybe Ripp makes sense.
