Need a tune?

[dboyle23]

Well, I am going to install a fuel pump in my gf's dsm, then we are going to put in a big 16g. My question is, I believe I will have to tune the car after the new fuel pump is in right? Also, can I just use an safc for that? I only have a narrowband on her car so I won't be able to get a great tune or anything like that. After that, installing the 16g i know would require a nice tune to run properly. But how would it run without a new tune? Just run it at the same psi as the t25 is running now.
What do you guys think?

If its is a 190 just keep the psi under 13, if it is a 255 you need to buy a fuel pressure regulator and you still need to keep it under 13psi. If you turn up the psi more you will hit fuel cut, i recommend a fuel pump rewire when changing the fuel pump or even with the stock one.

If you want more than 13psi u need a tune and bigger injectors, but as long as you keep the boost at 13 or lower you should be fine.

you shouldn't need to tune for fuel pump.

If you have a 255 you will need an AFPR,

I have a aeromotive fpr with gauge and thats obviously really simple to read. Its kinda pricey tho. But for your situation, I think you be fine as long as you dont crank the boost up

Right now she has full 3" exhaust, rai, uicp with 1g bov and boost control. Would a 190lph pump and the 16g at 13psi be a nice boost in power? We're running the t25 at 15psi right now.

Thanks guys, I appreciate the help.

EDIT: Also, how much HP will a 190 handle? We plan to upgrade some more in the future.
