I installed chicken ears stage 3 intake maganflow exhaust and chiped my truck with the diablo programmer and dyno tuned.. and my mechanic is saying i have to run ultra 94 gas.. but what gas is the best for a truck around 470 hp

 

eh..

you only have exhaust, intake and a dynotune, and you are putting 470 HP to the wheels?

I'm putting 420 to the wheels with 93.... and I think the most I have seen with pump 93 octane gas is about 650.....

 

HOLY COW !! 470hp with an intake, exhaust and tune.....man give me the number of your tuner!

















.

 

As much octane as you can feed it, if 94 is available in your area YES you want to use it. They took 94 away from us in NY 2 yrs ago so I now use 93 (but I mix in some 100 Octane every 2 or 3 fill ups)

As for how much Octane can handle how much HP thats kind of a loaded question. A Big *** KB or Whipple can be de-tuned down to 9-10 degrees of timing and still put out close to 600 HP on 93 octane (of course as said if 94 is available you want to use that), but pushing a smaller SC to say 550 or so may require 16-19 degrees on a street tune, which may give you trouble on 93 ocatane

 

its because i dyno tuned my truck this guy has a 6 sec civic not that it matters cause there gay ..lol but the guy i am with makes horsepower out of anything... he is very good at what he does ...its splitfire performance....

 

It's called the "Dyno mod" where the Dyno operator alters the SAE correction factor to inflate your HP numbers into BullShat land. NO Lightning will make close to even 400hp with only an intake, exhaust and tune....period.

You should go somewhere else for your tuning, you are being scammed big time by your current guy.

 

I run VP 112. Have not had a problem yet. It is actual called VP supreme. The reg VP is only 110 octane. I get it in burlington at New England Race fuels. Just picked up a fresh 110 gallons. Gotta love the smell.

 

thats not so true. a buddie of my had a 02 ported eaton a single blade t/b long tubes high flow cats. power cooler, an a tune and he was purdy close to the 400 mark.

 

HI!... Well I made 354RWH.P with no SC'er. no turbo, and no nitrous. All N/A baby! LOL!

 

Wow, I can't believe no one has said the INCREDIBLY obvious yet... you should be running the octane gas that the tune is meant for. Running higher octane fule is not always better, in fact it isn't unless the tune is meant to be running that octane fuel. higher octane doesn't just mean more power, there's more to it than that.

but to keep it simple, ask your magic tune man what he set your truck to use (If he is so good, why the hell didn't he tell you what octane fuel you need when he was done tuning it? )

 

My street tune and street nitrous tune calls for 93 .

If I change to the track tune its supposed to be at least 106 , we are lucky ,

we have 112 locally and yes , you gotta love that smell !!

SC

 

620hphoss. What are they wacking you down there for 112. Payed 670$ for 110 gallons here.

 

Dyno hp/tq #'s are worthless. The ONLY thing a dyno is good for is tuning I.M.O.

 

Hey Lumadar, I think the mechanic told him to run "ultra 94".... It was in his post...."my mechanic is saying i have to run ultra 94 gas".... I was thinking his mechanic and tuner were the same person...maybe not.

 

Well, I couldn't tell if it was, if so he called him a mechanic in one part and his tuner in another! Sounded like two people to me...

Regardless, if the guy is so good why is he doubting him and asking us?
