Recently I've done a few more of these setups and have been able to run more ignition timing with high boost. im starting to wonder if all that blow by you've had since day one is something more serious.
That aside Im ust happy your car cold and hot starts correctly now
Send over some updated datalogs when you get a chance, include the cruise control stuff we discussed

A motor that runs too much retard is just as bad as one that runs too much advance.
You cannot properly tune ignition timing on the street.

Car won't accept anymore timing with out knocking.
Turning the boost down and raising the timing just caused more knock.
It clear that who ever put the car on the Dyno didn't load it up correctly..
Wavy dynosheet isn't from a lack of timing but from how the car is strapped.
Wish a datalog could have been produced when the car was on the Dyno and I hope some day we can see full dyno run.
A simple EBCS can be hooked up to prevent boost spikes and boost drop off.
When I was street tuning the car I had suggested putting in a larger spring.
That being said, you can 100% properly tune ignition timing on the street...
