Ok guys so im a little confused here. Any help would be really apreciated. I have a 2011 gsr with an ams intake, uicp, and widemouth down pipe with a 3.5in qtp cut out replacing the cat. So i did a pull to see how much power im making with the stock rom settings and this is what i got 296 hp and 290 tq with closed cutout and 328 hp and 309tq with open cutout (attachment 1).

ok so i installed my wideband and got the boost reading correctly and started tweeking the afr, mivec, timing, and boost maps and did another pull and this is what i got 339 hp and 353 tq(attachment 2).

So i tweeked the maps some more and ended with this 324 hp 303 tq (attachment 3)

Then i decided to do a 4th gear pull and these where my numbers 328 hp and 319 tq (attachment 4)

Now my questtions are, why am i making less power when its the same temp outside on a tuned map than i am on a stock map? or was my car already maxed out from the factory? and what changes can i make to my settings to make more power?

 

Either the tuned map is crap, or the stock map is too dangerous. (i.e stock map may have too much timing and be too lean for your setup).

 

would you consider this dangerous for a stock map?

 

did you check fuel trims, reset them, rescale the maf, check them again, then adjust timing, etc?

 

i checked my fuel trim and idle is at -4 and cruise is at 5, how exactly do u scale the maf?
