"Standback Tuning For Dummies Guide" The Official Q&A...

I figured since both laloosh and CPE were responding in this thread I would add my datalogs and see if I can get some input also....
I used the boost air temp parameter since that is what laloosh's thread had, I changed it to fuel pressure now though in my dashhawk....
This is on the 17 psi setting with everyhting else zeroed out....
My only mods are a cpe CAI ,step colder HKS plugs and the RPMC turbo inlet...
There are 5 logs here. The first three are 3rd gear WOT pulls, the last two are 4th gear WOT.
Any input would be great.
Thanks in advance...

OK, first thing, lets get rid of the boosted air temp and replace it with DI fuel pressure and do your logs in 4th gear. We need to see what you fuel pressure is like.

Looking at your first 4th gear log, I notice you are experiencing knock. That could be due to your boosted air temps (hot air). I would try and lower your boost to stock levels since you are still using the stock intercooler. And I would log again to see if that helps reduce the knock.

Personally, I would tackle your AFRs which are out of control. I would shoot for 11.00 - 11.50. But that is up to you how far you want to go. You want it to be a less steeper slope; almost a straight line (in layman terms).

OK, I changed it to fuel pressure and am on the 15 psi map.
These are 4th gear pulls.
