Won't do a Burnout..

[bowtietillidie88]

Hey everyone.. Let me start off by saying this forum is awesome! This is my first post. I have a 1997 Tahoe that needed work when I bought it. Had a cracked block so pulled that and bough a fresh short block that was .40 over. From there I had the heads fully rebuilt and worked to support a mild comp cam (I don't remember exact #s) New spider injection system.. Only thing that was reused and not new was the motor mounts. New fuel pump, oil pump, all new lines hoses and gaskets... Long tube headers to dumped flowmasters mufflers no cats... I'm sure I'm missing something. With all that being said, the tires are 285s and for fun I tried to do a brake stand burnout (In a private area completely safe), It revved up to about 2-2500rpm and nothing. Not even a slow spin or chirp! I thought it would be easy.. Runs great down the road, feels good.. I have had many vehicles and have done many burnouts HaHa.. I just don't think this is from the stock gears, just don't know what I'm missing. Any help would be awesome! This thing is a fun weekend toy.. Hope all that made sense. I will post pictures later. Thanks everyone! Happy 4th of July

Did you have the computer tune for the engine work?

I did not get it retuned.. I honestly didn't think I needed to since nothing too much over stock was done. It runs pretty good, gets up to 75-80mph on the highway no problem.. The engine light is on but only code is for an emissions item which I don't need to pass inspection. Would a tune still change a lot?

It should help a lot

And how did you set your timing

The same shop that rebuilt the heads and helped me pick a cam based off the work they did.. Went back and had them dial it in once I had the exhaust and O2 sensors installed

Is Black Bear pretty much the smartest tune to invest into?

The forum has a lot good to say about black bear and they are a vendor here from personal experience I couldn't tell you as I do not have any tune but if I got one I would get black bear and what do you mean they dialed the timing in do you know what they set it at

 

[bowtietillidie88]

I will confirm on Tuesday but I'm pretty sure set it at 0°

Does the gearing need to be upgraded if I'm not running anything bigger than 33" tires?
