97 Yukon GT

[2dooryuko]

Hey all im new to the forum and i found that alot of people in here actually know what there talking about unlike other forums....

 

I currently own a 1997 2 door Yukon GT,

 

what im looking to be able to do is,

 

spin the tires like crazy, as of right now it doesnt wanna make them chirp, no matter what i do, the only thing that works is going around a switchback and flooring it from the start. i would rather have the ability to floor it, spin the tires, and go in a straight line instead of turning to get them to spin,

 

the truck stops accelerating at 90mph, i know alot of power programmers remove the top speed limiter, i was wondering if theres anyway to plug in a laptop into the car and change top speed limit, ecu, fuel curves etc with software and a cable?

 

next thing is i have an extremly powerful stereo, i have dual battery trays but only one battery, i have tried searching around for a dual battery kit to connect in another battery and have no luck at all, anyone got one? or know where i can get one?

 

i have a k&n cold air intake and love it

 

i am looking to get an exhaust, theres a guy in my area that does nice work, what im aiming for is 2 40 series flowmasters, 2 high flow cats, and 2.5 in tubing, dual rear outlet....

 

 

hope i gave enough info let me know what i can do!

If you got headers, and probably a cam upgrade with a custom tune would do it.

There is a couple of companys that make the software you are talking about, If you search around some forums somebody should be able to point you in the right direction.

Check your gearing. If it has 3.42s switching to a lower gear would help more than anything.
