Thanks Nick for all your help, I'm looking forward to getting that JDM tune loaded up.

talk about a success story! and this is why you get a vary reputable shop to tune these cars, good job JDM. Op great choice on blower, it looks great under there and clean install. im glad you got everything worked out with the tune as im sure you were frustrated as hell
Tq seems a little low, do u have a pic of the graph ?
Looks like the dyno operator either rolled onto the throttle or the clutch was slipping a bit in the low RPMs. That may have skewed numbers just a tad. This is about what I would expect for our base file (safe). The 3.375 pulley on the Whipple is comparable to a Roush TVS with the 85mm pulley. If you drop down to the 3.25 pulley you will see boost pick up to 9-10psi and pick up about 20 more hp and 30tq on the same tune.
The dyno operator also cut the run short. The car will pull all the way to 7400 possibly increasing your peak power number as is.
Mostly seeing 6-8 psi on the boost gauge. Seems low to me, could it be because of the stock cats?
That's a nice smooth dyno graph for a mail order tune !! How's the throttle response ? Do you really need to get into the throttle before "feeling" any boost ? I have a Roush TVS and it's a little soft, even with their Phase 2 set up.
I need to give Nick at JDM a call !!
Got the smaller 3.25" pulley installed a couple days ago and loaded the revised JDM tune.
Felt stronger and today I got my feelings verified.
Went from 560 rwhp & 456 rwtq with the 3.375" pulley to 591 rwhp and 505 rwtq with the 3.25"
I'd say I'm pretty stoked with those numbers
And of course, a video

And the old-vs-new numbers ... 560/456 w/3.375" pulley, 591/505 w/3.25" pulley
