Awesome numbers. I've been thinking of going procharger again.
Can you give details on headwork? Who ported, what valves and springs etc?
What cams you running?
Thanks
I think I've pretty much decided to get an aluminator short block. That'll be good for 850-900 whp and that's a strong street car engine. I have a set of heads and that will make a shorter downtime.
I'll either sell my current long block or keep it for a spare and maybe build an all-out sleeved...

The only 1/4 pass I've made.

Yes it is worth it to get a tune for an auto.
I would say an SCTx4 would be best but some like the Ngauge better because it is better for datalogging.
Just make sure your tuner will work with Ngauge.
Don't use the "canned" pre-installed calibration that comes with the tuner device.
I currently...
So what's the deal with the "upgraded" parts?
Did whipple change some parts, add parts, replace parts in the last year or so?
I bought my kit in Oct 2015.
Have you moved the adjustable idler? Are you sure it's torqued properly and not slipping?
I've used the same belt with different sized pulleys with no problems.
With a 3.75 pulley you are around 10-11 psi depending on max rpm.
Either the boost gauge was bad or the dyno software was bad.
Are you ready to swap the 3:73's yet?
(what's a "hearder?) ;)
Was it the same dyno before and after? It's hard for me to believe the 657 number and that big of a jump from the changes made.
Either the first dyno was low or the second was high.
I have been told by tuners and read many threads that 47lb injectors are good for 600-625 max with a BAP
650+whp...
657 at the wheels with 47lb injectors and no BAP???
I know two popular tuners that would not tune my car without ID1000's and a BAP at 9-10lb of boost. Hmmmmm
No dyno numbers but I can give track numbers.
