I'm having a bit of trouble getting my hp/tq graphs smooth, driving the car feels great, but when I plot a run in DLL it gets very choppy in the upper rpm range. I'm a self-tuner and still in the learning process so bare with me. I'm pretty much running the mods in my sig with the addition of an ETS 4" FMIC, ARP head studs, and some denso IKH-24 plugs gapped to 0.022. I'm currently running 29psi with 75/25 meth/water with crappy 90oct at the pump (Jamaica).
The logs look pretty good with just a few counts of knock in the mid range (1's and 2's) and my AFR is pretty straight, not perfect though. I was told by a couple of the big tuners that the stock ign system is working overtime now that I'm running such high boost plus the addition of water...but I've read on the forum so many people running even higher boost on the stock turbo/ign with meth and don't have this problem.
Here's a log on a 3rd gear pull, this is actually one of the cleaner runs...is there anything obvious that jumps out at you? Any help would be greatly appreciated.
