Don't know much about these numbers but are these taken with the car moving? I keep thinking of Pontiac Ram-Air... haha. Does that matter?

On a side note. We have a few different RHD headers available in Australia if you are interested. Well worth doing due to the smaller diameter pipe used in the RHD stock manifolds.

As in the UK we do not have headers, do you know if LT headers also help improve flow of the intake?

In theory they should do and even more so on a RHD car as Ford crippled our RHD headers. :(


P.S. Was your stock 42lb/min@6400 also on stock headers?

The X-force rhd headers are a thing of beauty , work of art even :-D
Still have not got around to fitting them though.
google ES-FM15VMK-EBS .

The only problem with the headers is they are only compatible with their own cat back systems.

The Sydney HQ will ship direct to us here in the uk.
Took less than a week :-)

49.40 @7576 rpm , my stft was 1.05 in this cold air ,so close to 51.8 corrected
What's the calculation to correct the MAF based on STFT?

Log shot from last night. 94* ambient air temps and 65% humidity. I'm close to sea level (30ft above) but DA was 2800ft according to the drag times DA calculator I used. Corrected to 0 DA this is about 49 lbs/min through the stock intake manifold. IATs as logged were 100*
Edit I found a calculator. Relative density is 92% which means I'm at 92% airmass I would be at 0 DA which means 46.6/0.92=50.6lbs/min corrected for DA. I technically need to remove 2% for my -2 STFT so actually 0.98(46.6)/0.92=49.63lbs/min corrected for total fuel trim and DA!
Use this calculator here. To calculate your DA and relative density so everyone has fair numbers.

Are you doing remote tuning sessions with lund or just getting them to adjust based on datalogs? My VCT didn't seem like it was changed much when I compare my Boss logs vs stock mani logs.

Adjustments , I just did a new one . Throttle response is leaning toward violence . Max advance is rapid and airflow is up to 52 at 7500 . .99-1.0 corrections . I'm excited to track it
