who makes a bigger throttlebody for blazers?

 

You'd have to sit down with your local machine shop to get something like this. The other problem with putting on a larger TB is that the hole in the UIM is sized for the stock TB and would also have to be opened up.

 

i see. sounds more like a pain then anything. how much power increase would it give me anyway. probably minimal and not worth having done. right?

 

It probably would be a decent increase, but for the $$$ you'd spend, it would be quite cost prohibitive.

 

Better off getting your PCM flashed.

 

what do you mean by that?

 

how hard would it be for the machine shop to do it?

 

You can send your PCM out to get reprogrammed. Or buy a flashed PCM and pay a core charge until you send in our old one.

They hook it up to a computer and recalibrate it. Usually you have to run a higher octane rating because of the adjustments made by the flashed PCM.



here's a link about flashing.

I dont know anyone who has done this because alot of guys like to buy Hypertech or Diablo Predator programmers. I was going send my PCM to them. Instead I bought an upper intake manifold for my Impala. The repairs set ya back when you wasnt toys.

 

A few other companie that do PCM work.
