Hey everyone I recently installed a nitrous system on my friends wife's TrailBlazer SS and we finally got to take it out to the track to see what it would run on a 75 shot.

So the problem is when we launched it it tryed to take off nicely but then bogged. it jumped about 3 times then we turned the nitrous off to finish the pass. Then we were messing around on the highway going home and when we sprayed it it goes to 7k rpm and over revs.

So my question is what can i do to fix it where it launches and wont over rev. Ppl have told me to get a window switch and program it to spray at certian rpm's but the funny thing is, I have the same kit on my 2000 Silverado Z71 spraying the same 75 shot and my truck takes it fine. it launches nicely and it shifts like its supposed to.

Any and all help is appreciated

Thanks,
Steven S. Davis

 

Check out TBSSowners.com and TX-SS.com. Several of these guys are spraying so they can probably help you.

Other places that could help are NitroDave's in Waco for N2O specific questions and AMS in Lewisville for TBSS questions if you feel like giving them a call.

 

Thanks bro. I'll try some of those sites and i'll give nitrodave's a call.

 

the stock tune will not spray through the shifts ...

get a pcm/tcm tune and a servo for the trans...

also a trans cooler is a good idea... before you kill the stock trans
