Adding Midpipe. ow much fuel I need to add with the PIM?
 

Greetings

I ordered a resonated midpipe and I am wondering how much fuel I need to add with the PIM voltage. Also do I need to back up the timing a bit on the PFC?

Mods are:

-Downpipe
-Apex GT cat back
-Y-pipe
-Intake

Any suggestion?

Thanks all!
Serge

Yeah, what he said ^^^ Serg, you runnin your stock motor? if yes, how many miles you got?

What's the meaning of that shit? Yes I am running my stock motor with 18K miles.

OK, no one bit the question. Here is a rough estimate.

They advertise about 20HP gain on a modded engine with a MP. Yours maybe 15HP max.

15/255 = 6% power increase. Add 6% fuel then have the AFRs checked. That should be very safe.

Serge, don't take offence bro...the :withstupi icon is just saying I am in the same boat as you...Ok, just so I don't have to translate "in the same boat" I mean, I have the same problem as you do :) and would like to get a solution.

Oh.. OK. Sorry.

:D :D :D

ok
 

OK Thanks. And now What about the timing?

Thanks again
Serge

Hey Serge,

Re: ok
 

yes, what about timing? Should we just leave that alone?

...
 

Anyone??

Thanks
Serge

serge..i left the timing alone on mine and it's been fine running about 11-12 psi of boost.

Allright. However I am running 15 PSI on my BNR stage 3 so I am wondering if I have to touch the timing a little to get the most of it.

Thanks
Serge
:D :D :D

I just swapped out my N-tech HF cat, that flows pretty well - supposedly 96% of a midpipe, for a 3" SS midpipe and I didn't add any fuel to my maps.

I have a WB set up and my AFR's are still safe(11.4-10.8)
It also helps that my maps were pretty rich up top. My knock kreadings also haven't gone above the normal 33-37 level.
