HP loss without tune?
 

Hey guys, Im running a basemap right now, ls motor on 8psi. My timing isnt set right either ... around how much whp am I loosing without being tuned?

B18b1
t3 .60
8psi
440 injectors
inline fuel pump
arp head studs
2.5" DP with 3" back to ES mufler.

I hope this is a legit question .. I know hmt dosn't like the "how much hp will my new ____ give me?"Q's.

depends on how far out your base map is, you will definitly see some gains though ;)

It was a basemap from xenocrome when i had a .48 .53 t3 , and stock exhaust .. so its got to be pretty inacuarate...

Re: HP loss without tune?
 

yes but basemaps are rich with backed up timing so there safe. not the best for perfect hp or drivability.

get it tuned crank up the boost. 12psi is the minimum allowed boost on a LS ;)

Could be a lot could be a little...

Street tuning the AFRs will definitely pick up quite a bit for you and most importantly give you piece of mind with safety. ;)

I agree with this guy.

and 15psi's minimum on an ls/vtec

ya lets run more boost with more compression, you jerk off, ls can run high boost stock cause they are low comp, just tune that bitch good and go for it, 10:1 is around what a stock lsvtec is with either a gsr or b16 head on a stock ls block, yes i know gsr cc's are a bit smaller but both are around 10:1 i wouldnt run more then 12psi on a lsvtec unless that bitch was built. on ls's ive seen as high as 18-19psi on bone ------- stock ones. haha but ya to answer your question you'll definally notice a different, every motor is specific to itself, no stock b16 will run the same and tune the same as another bone stock b16, every motor is different and even though your basemap would more then likley run it fine, you could deffinatly use some adjustments and notice alot more.
