300@wheels STOCK with intake and exhaust only. stock boost. notice the fuel cut. i think i have a bad map. the car runs RICH ALL the time. real rich. the car will throw the code for turbo pressure sensor when this happens. it happens at full boost and full load only. like i said i think it is a bad map sensor. any ideas from you? the dyno tech said i would have hit 320@wheels if this didnt happen. i still had another 1200 rpm to go. i must have gotten a good clip from jarco

 

sounds liek it... very impressive

 

mmmm.... the air fuel is 13/1..... thats far from rich.....

 

Yeah need to be careful with your A/F I'm hoping this was with race gas.

 

stoich on pump gas is around 12/1

 

no... stoich is one pound of fuel for every 14.7 pounds of air...

less than 14.7 pounds and its "rich"... more than 14.7 pounds and youre "lean"

13:1 on a stock motor in stock trim and stock tune is fine. when the boost gets cranked and running hotter IAT's, then running richer will be necessary.

 

you learn something new everyday. thank you

 

get a S-AFC and you should be able to take care of the fuel cut and the lean run condition. and make shure your fuel pressure is where its supposed to be.

 

stock fpr. could that be wack?

 

stock fpr could possibly be a culprit of running unusually lean... but it wont cause fuel cut.
