I have seen recent posts regarding the current fad of "locking" the secondaries open. It seems that most agree that ideally the secondaries should remain closed off the line, but should open much earlier than the stock ECU calls for. My understanding is that the Superchip reprograms for a 3100 RPM opening. But many have stated that this may even be a bit "late". I am having a Superchip custom programmed and thus I can specify a particular RPM for the IMRC to open the secondary intake runners. I would like to get everyone's thoughts on this issue as to what RPM to specify. Please keep in mind that I do have a KKM, 75mm Pro-Flo MAF, SHO-Shop Y-Pipe, hi-flow cat, Bassani cat-back, and SHO-Shop pulleys. I will probably upgrade the throttle body if I can get some conclusive results on the Mustang TB changeover or if there is an aftermarket unit. Thanks for the input guys.

i can get an eec tuner, and do a series of dyno runs to find the best time to open them at, if you would like...

If you're willing to do that Bret, that would be very cool of you. It sounds like a lot of trouble, but I'd certainly appreciate it. Let me know. Thanks.

yeah, let all of us know, so we can get superchips programmed the right way.

It is probably sweetest in the 2800-2900 range. I can sure feel a difference with the superchip -- much smoother rpm build through 3K-4K. If only it didn't detonate so badly at 4300+ rpm.

Somewhere between 2700-2900.... Do two dyno pulls, one with them pinned and one stock. Just find where the "pinned" setup starts gaining power over stock and you've got your ideal rpms....

-Lance Yeah, that was my problem when I got my Superchip...code SFG0. Nice to have the Secondaries open up early...sucked that it detonated at higher rpms...even with Sunoco 94.

Your combined use of the Superchip AND an aftermarket Mass Air meter is probably causing a lean condition where the detonation starts. When running a custom chip with an aftermarket MAF, you really need to check your A/F ratio with a wide-band O2 system.
