First pass 12.79 at 103
2300 pulse 29psi.
Adding more fuel boost and timing.

Ran exactly the same with 150 more pulse. I'm going to set the pulse width to 2400 and bump the timing some more.
Intake temp is 100 degrees so it's warmer than usual.
It's not looking too good. :eek:

So it seems to spool quicker but yet runs same et with same tune and temp is warmer?:eek: all the time to install. Hard to make worth while with those results. I was wanting to do this to but unless u get better numbers I may not.

bad thing about testing is when you go to the track different day= alot of different variables
track temp, air temp, track prep etc

maybe he could post time slips of before and after and we can try to judge it by that

they are the same... Don't expect a .3 reduction in ET from a hot day to a warm day.

well he did say temps were a bit different, like i said really hard to judge track times from different days just in my experience anyway.

On second thought this mod might not be dead yet, at least for the lb7 crowd. Im hoping the reduction in drive pressure will greatly improve the efficiency map if our stock IHI's........yes i know im grasping for straws :eek:

So on a sea level track with warm temps what is your guess as to what it will run? Its not like we are used to running 50*F and it was 120F* today LOL...

Temp - 83
Humidity- 43%
Baro - 29.96 Hg
58
72.3
94.31 %
DA- 1992 ft.

That was at 5pm today so sure the Air Density was a little higher but 60' was good 1.67. You really think he should see .3, .4, .5, .6 when DA is 1000ft? I think not. My truck doesnt give a shit about how hot it is. It is VERY consistent

My truck is very consistent too, but my dad picked up .3 between 2 weekends ago and last weekend. The only difference is temps were about 15 degrees cooler and less humidity.

sorry i must of missed where he posted all the info, i really didnt have any info of what track, elevation, DA etc

But here in idaho ive seen pretty big difference in running one weekend vs another without making any changes, some could be track prep some could be weather changes

Don't get me wrong im not saying track conditions don't make an impact but rather feel kinda bad for Anthony R&R of a turbo + wheel cost of 400$? and literally no gain first time out... I'm glad this was made pubic now lots of guys won't drop the money when it isn't going to give them the gains they were told.
