Im trying to launch it at 20 psi but it wont let me go past 10 without defueling

The RAD box will work for your truck. It makes the ECM see 55MPH at all times so it doesnt defuel at any boost level.

Are you sure the ADR w/ Pulse doesnt get rid of it? I will have to try it tomorrow but when i power break it i normally ignite the tires...
I have did it to get a picture once in 4wd it fueled hard... Too hard... It actually stalled out when i got off throttle! LOL! :humm:

the adr should get rid of it or atleast i know the adr 4k does. mine will tag 20 psi in nuteral, just reving the engine. and that is on a mechanical boost guage not the adr monitor. the smarty on the 99 will also remove it. and the 99 is a lot different than an 01 02 truck it doesnt have the same tqman that they have. 99 are striped down on the electronics side of it. i mean the dont have a speed cut off like the 00-02 does just a defuel point. so its kind of hard for you guys driving the 00-02 trucks to compare to the 98.5-99 trucks. and unless you have billet shafts in your tranny and a billet flex plate i would not go above 10psi on a launch. it will shear the shafts at that boost level. thats where the tqman is handy cause it will help save the trans and keep you from exploding it.

my stock output made it till 600hp and then blew. was doing 20psi launches for a year and a half then went compounds and bang

well yours made it better than mine. i broke 4 of them boost launching. and one input on a roll race. and 2 flex plates. the last flex plate was a billet one and i still twisted it in half. and 600hp is that by your estimates or a dyno proven number. because acording to sun coast and ats a stock shaft is only capable of 450.

Im sure a tranny parts company is gonna under rate parts to sell theirs or make theirs more appealing.

I definitely dont have a SPEED defuel. Been over 115mph hehehe! :yeah:

that was dyno proven numbers running 12.39 at the track. but I was told I was very lucky to go as long as I did. I have a stack of dyno slips and you can call the shop in my sig and ask them all about my truck. I don't estimate I put up solid numbers and give advice based on my experiences. I went almost a year with 488hp at the wheels running 12.92, then went to 532 running 12.74for a month then compounds and 575 for 2 weekends at the track running 12.52. Then it made 603 hp and 2 good launches at the track the third went bang. Now billet and a full year and half on 603-683 hp. Sorry I don't put up with bs from people if you read my signature you would notice that I am not full of it.
