TitaniumTT will become famous soon enough
When you head back to Daves, post up with a date... I might be able to head out there. I know I'll be out there on 4/16 for a tranny swap and a dyno assuming the tranny swap goes smoothly.

Good numbers for sure especially at tht boost level.

Feel free to add to the good guy KDR/Speed1 thread

Magnaflow makes a cat, I welded that up to some piping and some v-bands so it could be easily swapped back and forth.

The earliest I'll get back to Dave's will be this summer, after my next MD emissions test gets done. As easy as it is, I have little time to do the emissions swap over twice. See you at DGRR-XI.

Yup, that's what Dave & I thought. With the 720cc injectors in all 4 holes and the supra fuel pump, Dave's tuning of my Rtek was pretty much all in the lean direction to hit his AFR targets, meaning there's lots of room for improvement once the boost can be cranked up. I'm starting to think it would be worth it to get an add-on boost controller to push a little bit beyond the stock 7~8psi levels, maybe up to 10 psi. At that level, I'm thinking the stock TMIC will be my limiting factor.

Will do, Dave's stellar reputation certainly doesn't need it, but IMHO there isn't a better tuner/rotary guru in the community.

Given I only have to deal with emissions testing every other year, I won't bother with an aftermarket cat. I'll just do the pre-silencer/Mazda cat swap over for the sniff test. The stock Mazda unit I've got may be too restrictive, but it still works well as an emissions device. Dave says I'd pass the testing with flying colors.
