turbonetics 55mm inlet ball bearing turbo (t04b?)
welt chips
billy boat catless exchaust
i got 226 whp 216wftlb and average air fuel ratio was 10.5 isnt it kinda low?

That does seem low as far as peak power is concerned

I'm interested in what you get after the a-tune with injectors because thats what I have

Fuel ratio should be 14.7 at idle and cruising 3k rpm.

At wot you want to see 11.5-12.

10.5 is very rich and you are leaving power on the table.

Go to Roguetuning.com and buy the M tune! You will thank me and Joshua if you do!!

Have you tried both? The A-tune is a hell of a bargain with most of the functionality you get with the M-tune and sometimes its hard to justify spending almost $1000 more for just the maf.

seems a little low for peak horsepower.... but with it only being 14psi the question also lies in the spec of the turbo. At that current rate 17-18psi should yield around 280whp

Also depends on what his goal power is, if its above 300whp then yes the AFM maxes around 330whp.

After ill get the rogue a-tune ill dyno it again, later on i might buy the m-tune to get rof of restrictive afm, i tryed turbonetics indentify your turbo link but they have closed it down.. :/

I was thinking that with stock injectors i should be leaning out at high rpms.. what can cause this running rich problem, cause even my narrowband shows im running rich in wot

the richness can come from the chips. Stock injectors are good for around 280whp, I assume that number is with a 3bar FPR. What power goal do you have currently? Honestly with Josh's A-tune, new injectors, 3bar FPR and map sensor you should be around the 280-300whp range with 18psi, assuming your turbo is around an #8 hotside (stage III turbine) with a larger than stock compressor wheel which yours is.

Im am a really big noob when it comes to the turbos, one thing im shure of its bigger than stock im having issues with clearance in the inlet side it touches my alternator and on the hot side im having issues with the exhaust pipe wich go to the turbine touching my steering shaft..

But im pretty shure cold side has ball bearings
And its water/oil cooled
My goal for right now to max out whp within stock afm limits and still have reliable as it is right now

Yes I have tried both.

What I found with the A Tune was that the turbo was out flowing the stock AFM and I was leaning out above 12.5 at 4800 rpm. The MAF fixed that and I am REAL happy with the current performance and ability to turn the boost up another 2 psi.
