Tuner problems

[BrokeAssPainter]

New to the forum so not sure if anyone has asked this question yet, but I just bought the quadzilla adrenaline with iquadbt. It's flashed and installed but I can't for the life of me figure out how to tune it so I have some form of power off the bottom end, I mean I hit the gas at the light and it takes like 10seconds to get rolling...... Any help at all is appreciated, I'd hate to mess up my baby

You've got 35-inch tires. I'm going to assume you got 3.55 gears. That means your final ratio to the ground is 3.21:1 which is too tall of the gear ratio. The only way you can fix this problem is to get your final ratio in the 3.55 to 3.73 ratio. You would have to change your axle gearing. 

 

Like myself, I gave up the 31-inch tires (265/75 R16 or the 235/85 R16) and dropped to 30-inch tires (245/75 R16) which now makes the final ratio 3.69:1 and this truck rips. Half throttle on dry pavement it will spin the tires.

 

Your problem is the tires pure and simple.

I'm wondering how you got 35" 20x12's on a 2wd without ripping the fenders and bumper off of it?

 

On a more serious note...your 2 options are to go to a smaller tire like Mike suggested or upgrade to 600hp like I chose to do.  Either option will make the problem go away.  Smaller tires would be about $10k cheaper than the other option.

Man I bought the truck like haha, only thing I did was add quad adr lol kid has some BS pump on it, no plastic under the fenders, turbo ring pulled and he cut pipe right under back seat..... Damn thing sounded like a semi when I first bought it ?

Truck ran perfectly fine before I added the quad box, it runs like a raped ape past 2100rpm but it lacking something on the bottom end now, it took off fine before but now it's like...... Riding a dirt bike with the choke on..... It's weird and idk enough about tuning and all this electronic stuff to fix it on my own. I worked at the machine shop here for a while so mechanical wise I'm good but I had a hard enough time figuring out how to post on here much less figuring out this tuning gig ?????

Add fuel down low until you are happy. 

 

Follow the tuning article guide it outlines how to do this.

Ok, is there a tune I can download until I can get this one figured out? Thanks for all your help man, idk if I've said that or not yet but until I found this forum I was STUCK
