It's just weird that if you look at my boost and logs, it's right on. Anyways, from what Terry said you should be in 17-18 psi range. It's great meeting you, the VK IC did well.

Good to meet you too Phuc! If you look at your runs... the Dynojet has you at 15.67, 15.48, 14.14PSI respectively, but your V3 data logs show 14.5, 14.2, 13.2PSI. As the boost increases, because of the mis-calibration of the dynojet boost gauge, the delta between the actual boost and measured boost increases.

I see your point. I didnt have a chance to look at my gauge bcuz I was logging and that shiet doesnt have the recall feature . So what are you gonna do with that gauge since it's off as well?

nice numbers but i've gotta ask..... All these heavy hitters are running INSANE boost....
17 - 20 PSI on the stock turbos? Isn't that kinda high?? or are we just going for the Dyno glory runs...

+1 The dynojet boost meter was mis-calibrated and reading a good 2+PSI at times.

great meeting everyone. had a great time.


mark, you know what - after seeing alpinedevil335's dyno sheet and seeing his 19 psi, i think the dyno's boost reading might have been right. especially since he was one of those that dynoed later on the day. i remember awhile back when i had procede and a gauge, it was showing about 14-15psi on the boost and datalog but on the dyno it was a different story (17-18psi). who knows

ill probably have my car dynoed somewhere else to verify

Check out ontopofm's post on this link http://www.n54tech.com/forums/showth...?t=4439&page=2 his Procede logged significantly lower boost than the dyno and it's proven that the Procede log's a little higher than true boost... so, with all this info, I'm deducing that the dyno is a bit mis-calibrated. Regardless... good seeing you again Nico... did you end up going to the wedding reception?

It was a good day. I actually let a friend borrow my RevII so i had the JB3 1.3 on my car. The first 2 runs where map 7 and the 3rd was map 4.

oh yeah... it most likely is mis-calibrated then. im definitely going to get my car dynoed again soon. to see a more accurate reading of the boost also. i just ordered the new spark plugs going to have the downpipes put back on and throw on my forge dvs.

good seeing you too. yup.... got there around 2:45ish

Donald, thanks for hooking me up with the gt1 scan. Appreciate it and your car is badass as usual. Sounds great.

Rather than dyno'ing to get an accurate boost measure... just buy a boost gauge.

It shows 0psi at the beginning of the run

Looks to read fine to me.

Really what are you talking about? What does a BOV have to do with anything? This is a T-MAP car and cares less about how you vent the boost when you close the throttle.
