METH HEAD
I rolled on down to PMi yesturday with my brother and I have to say that I was extremely disappointed, to the poi9nt that I feel like never want to roll a wheel on that POS again. I spent the whole previous night tuning for it. I started out at stock boost and added or removed timing and the same with fuel. I got it up to 18 psi with very little knock and the truck felt awsome. On Data master, I was turning out 13.4's @ 97. I finally started getting some decent MPH. My 60's were 1.7 and 1.8's. SO I get to the track which is 1000' lower than where I live and everything changes, a lot. I lost 2 psi in fuel pressure, not sure why, my KPa's were just waaay different. At 17 psi here my KPa was around 197-199. Down there 17 psi was 211. I also noticed right away that the truck would rev to 4800 RPM to where as here it never goes passed 4500. So I do my first pass and crank out a 14.8@72MPH with a 2.1 60'
I was thoroughly embarrassed. I got on TP and made A LOT of changes according to my Data master runs. Surprisingly, Datamaster was almost dead on, it was +/- a tenth the whole time. Anyway, made some changes and knocked off 8 tenths. Ran a 14.0@95 with a 2.0 60'. Now, I was having trouble holding boost at the line and was having to launch at 5 psi when normally I can launch at 15+. I made a few more changes but ultimately I did myself in and ran slower. The battery in the laptop died so I couldn't change anything else. It just sucked. I drive 50 miles to get shit on. Sad thing was that the day started out @ 65* and I wasn't really able to take advantage of it. Oh well. I think Im done with tracks until they build one here which will more than likely never happen.
