Dynoing this friday again
Well Im getting my new ecu tunned by Scott (boostedmaxima). I have Iskey racing cams for my boosted app.(258/270) I have the vg30e 3rd gen. I have ported intake manifolds im running a stock ct26 at about 14-16psi. I have the heads ported and polished. Im running a 3 inch down pipe(no exhaust)
I have the redline bumped to 7000rpms.The last time I dynoed on a stock motor with no port work or cams I made 240whp at 10psi and help peak power till redline of 6000rpms.
So where do you think the power will fall off at with the 7000rpms? Or will it.
Im dynoing friday. So make your guess now and ill let you know if you were right.
How much power and torque?
And will power fall off and where?

Remember.. 45-50 idle fuel pressure.. and i would lean tward the 50 just to be safe. O and i Added a BUNCH of fuel up top so if you really rich on the dyno, you can lower the fuel pressure just a bit. But untill you know if your rich or not leave it at at least 45 psi base. And if your really rich you can bring it down to at the lowest 38-39 at idle.

Maxmaxima actualy did 99% of what you've got there with the ECU I sent back your direction.
I struggled with it for quite some time not knowing it was a Automatic ECU and trying to make it run with a Manual Base program. That does not work to well.
I've not pushed my car real hard like your going to do on the dyno. And I've never been on a dyno so not sure what's going to happen.
Like I've said many times before start out safe and tune from there. Would not slam a bunch of boost to it unless you know what your AFR's are.
If you do you better bring a hoover to sweep up all the parts that fall out on their floor when it go's boom.
Read the plugs .... Wideband and sneak up on the right AFR's. I hope I've made that clear.
Good luck,
