I was recently tuned by Scott at TTP. I have typical bolt ons... made 355whp. I am installing an AMS FMIC, hard pipes, and a EPM open dump 02 housing..... Will I need a retune, or should i be ok until i get my cams installed. I will be getting tuned once my cams are in, but wasnt sure if i would be alright with the 02 housing

 

The fmic and O2 housing can affect your AFR. Furthermore your boost curve could change where peak torque lands in the RPM band and the ignition timing advance for that area might not coincide with what is safe any longer.

When are the cams going in?

 

I would let scott look at some logs after you put these parts on and log the car.

 

To be on the safe side I would get a retune. FMIC you are going to flow a little bit more cooler air vs. the stock one. So yeah your AFR are going to be different. Re-tune it so it is balanced out and grab a few pony's while your at it.

 

Or put everything on at once, then retune.

 

why not just wait until you put the cams in then re-tune with everything?

 

Just log the car as stated and email the logs down to Scott. It shouldn't need too much adj. Best to always have the cars tune on par

 

alright, i guess ill be waiting
