i just bought a BRAND NEW zex kit off of ebay for a really good deal.

i had to capitalize on the oppertunity.

i have other mustangs, but this kit will be going on my 4.0 mustang.

the car has a CAI and a custom dual exhaust.

im only going to run a 75shot on this

if i am running the zex managment, a wot switch, and a window switch....

is a tune ABSOLUTELY necessary to have?

reason being someone stole my tuner, and not i would have to buy another tuner+ zex tune, and i dont have Allot to spend now.

i would not go indefinetly without a tune, but for the time being CAN THE CAR BE RAN ONCE OR TWICE WITHOUT A TUNE?

ive read from factory comment does not require any timing change or anthing for 75.

 

You can get by on the 75 shot with the stock tune for a while I would guess in the 4.0. In the GT with the 4.6 no problem alll day long. Need to pull a few deg. of timing per 25 after that. I would call Brenspeed and see what they say. I would get a tuner as soon as poss.

 

if i could find a good deal on a tuner i would, but then i still need a zex tune.

anyone selling a tuner for cheap?

 

You can run the 75 without it. Not like you spray everywhere u go.

 

ok so:

i CAN run a 75 shot on a stock tune...(as long as im not spraying everyday)

but...

When i get the chance, buy a tuner/tune for added safety


I MAINLY JUST WANNA TEST OUT THE CAR AFTER I INSTALL THE KIT.

 

i wouldnt run nitrous without getting a tune no matter how big the shot or how many times you plan on using it... but thats just me. it only takes one shot to blow your motor. from what i hear you should be fine..... but don't blame me if your motor throws a rod

 

Whats the change that something blows after i take just ONE run after i install it??

is there any alternative to buying a new tuner and getting a tune? im super pissed someone stole mine

 

haha just 1 run sounds good now since you just ordered the kit... how many runs do you REALLY think you will make after the install and before you buy the tuner just like all of us keep saying only 1 more mod after this haha not going to happen

 

Congrats dude...

 

Well let's say I rly only do 1 tops 2 runs. How will that be?
Some people think I don't need a tune at all.

What's the final decision.

WILL I blow my motor with under 4 passes on stock tune?

Should I never even think about sprayin without tune?

What do you think?
