Mods in sig. When cold the truck runs great. All kinds of power, will blow the tires off through second gear as long as you keep your foot in it but as soon as it gets some temperature in it the power is gone. Forgot to mention that it also has 30 pound injectors. Dont know what tune is in it as I just got it and havent had a chance to get it on HP Tuners but any ideas???

 

is that vortech intercooled? who tuned it? Has it always been this way? just started?

 

Non intercooled, dunno if its tuned or not and I just got the truck and as long as I have had it it has been this way

 

That sums it up right there. Those non intercooled vortechs are fire breathers. Once that truck gets hot is it pulling all of the timing out. Take it to a dyno shop and have them tune it for you.

 

Yeah I figured as much. Was gonna order an intercooler for it. Ill get on that tune and see what happens.

 

You might want to consider not going WOT again until you have it tuned.

 

I rarely do anyway. The truck is a daily driver/tow rig for the S10.
