Jet Performance Stage 1 computer module i had ordered a stage 2 but this company i ordered it thru closed down and didnt send my part so this guy sold me the stage 1 for cheap 120 shipped to me couldnt pass it up considering the chip i ordered is on back order until Feb so im going to be selling the stage 1 when i get my stage 2 if anyone wants to buy a chip

I know im needing to put some headers and i want to do a low end cam but im not to sure which would be the best for me ANY HELP PLEASE ANYONE!!!!! im wanting some low end any help with that would be awesome please help me out!!!!!!!!!!!!!!!!!!And would anyone know what rear end gear i have or how can i find out what gear i have and i want to know if some 3.73 rear end would be good for what i am wanting to achieve is to be close to around 300hp when im done i really want to keep my 4.3 i dont know why when i have always had 350s 0r 305s all my life i thinks it just that its a V6 and i think it would be sick to say its 300 HP 4.3 V6

 

You won't make 300hp with simple bolt ons.

If you are looking for 300hp, best bet is a supercharger. With 140K on the engine I would also go with a complete rebuild before adding a supercharger.

Oh, and get rid of that 160 thermostat. You'll be throwing codes before too long.

 

i have had that 160 stat in fora long timenow its been good so far i know im not going to get 300 hp with the bolt onbut alot ofwhat i got helped it get better mpg andrun better now im wanting to get it to that 300HP mark but i know a supercharger will do that but what else is going to help i been looking into theWynjammer superchargers is there any suggestions on a cam for what im wanting is the low end
