I guess I should have been more detailed. Post what engine its on like j9fd3s did.



I was thinking on dropping a 20b in but the milage on a ported worked on car with a 20b scares me.



maybe I'll stick to the stock... my goal is to make about 500hp under 20psi. Of coarse I will turn the boost down to 10psi on normal street driving, that or less unlese I need it.



I have a question, if I am runnig say 500hp, turbocharged, at 20psi, that would require nice fule flow, now if I turn my boost down to 10psi wouldnt there be too much fule now that the isnt enough air to balance it?

i asked someone about that . They told me u can have two maps saved somethign like that so a map for drag racing and a map for st driving wit the heltach.

hm, would not that requite 2 ecu's and then you'd just switch between them? or can have you have multiple maps on 1?

the fuel is addded by boost and load in most cases.

so it iwll compensate with fuel by knwoign how much air is going in and how much load

I found that if I drive like a total wimpoid, totally keeping off boost, I have acheived a personal best of 35 mpg highway cruising...

I use a haltech e6k, I have T04e 60 trim, no cats, just rear mufflers, and I use the FJO wideband for tuning...

My motor is a S5 with a large extend port..

I think this is where paying extra for the haltech over the microtech pays off, closed loop tuning has its monetary benefit when gas gets to the price it has, and having the wideband in the car all the time really lets you see where the car is running all the time, the off boost tuning with the FJO has saved me so much in fuel, its paid for itself really.. I use to drive my GX(n/a) when I was concerned about gas mileage, however my TII now is far better on fuel than my other car..Max

-since i got my car back, about 12-14mpg, i've been a pretty happy driver dispite my boost leak-

mpg...haha...what's that?? https://www.nopistons.com/forums/pub...1047683785.gif
