well I wasn't able to get in enough pulls on the street with the E85 before the dyno so it only put down 315whp/365tq which was kind of a disappointment but a fellow JB4 owner was there with me and has the same set up but data logged and tweaked before his dyno and put down 380whp (DCI/JB4). Needless to say he and I are hooking up the USB cable and data logging very soon Hoping for around 360whp after his tweaks which will be plenty good until it's time for catless DPs

yeah there's a ton of room for improvement The first thing I would have done even before the dyno is to start dailing it in on the street. I've done that with the help from Kalud with some settings here and there to get my boost curve to be set correctly so my actual boost can hug it better and get on the target faster ... but pretty much out of the box all my logs were spot on with not a lot of improvement other than playing with richer Fuel / meth concentrations and the timing curve i guess.

Good luck and if you ask me, the tuning is the fun part, not really the dyno numbers

Haha ya my buddy will be helping me data log and fine tune next week

His car put down 380whp on the dyno after his data log and fine tuning, so I am hopeful

so finally data logged with help from my friend who is a JB4 wizard, and he discovered that during the dyno it must have hit the peak boost safety and kicked down to Map 0. Which could by why I only put down 320whp. He said everything looked fine and I was still hitting 16.5psi on Map 5. He did a couple little tweaks to smooth out the power band and said it should be more around 350whp.

I'm hoping to hit the dyno again in a cpl weeks, hopefully for some better numbers
