Here are my #'s with budget HEADS! Tuning done BY VORTECH 
Thanks to him my car is drivable..
1993 mazda RX-7
01 LS1 with T56
28.8lbs injectors
LS6 intake, 241 heads stage 1 TEA Milled 0.030, stock valves
Cometic 0.040 Head Gaskets
intake exhaust
.100 71.0 52.6
.200 136.4 109.2
.300 207.2 159.1
.400 249.1 203.8
.500 280.1 230.8
.550 288.5 239.2
.600 291.1 245.2
CAM- Futral F6 226/230 .575/.595 112lsa
Also 1 7/8 LT's, 2.5 true dual exhaust with dynatech cats,85mm SLP Maf deresistorized, Billet flwheel, LS2 timing chain, Ported LS6 oil pump, ARP rod Bolts,ASP pulley, 4:10 gears, KAZZ LSD and Chromoly axles, and modified mazda driveshaft.
The car put down 416hp and 383tq.... still some tuning left to do, injectors running 101% duty cycle so I have to change them and once I finish porting my TB it should put down a few more ponies.
What do you guys think? Here is the graph.

Gomer the tailpipe wideband was out by a full point. Paul had the FJO in the car and watched it. Unfortunately we couldn't get the FJO to datalogue with the MPVI cable. Basicaly Paul watched the AFR and made shure it ddn't go over 12.5. We didn't play with timing either-there was a bit of knock but it was coming from one of the exhaust flanges touching the car. Paul I have an AEM wideband that we can use to datalogue whenever your ready. Get that ported TB done and fix the airfiler setup and I'm sure we can get another 10 more out of the car. Guys you have to see this car-it's mint black RX7-nice wheels crazy huge Brembo's and a slick roll cage. The LS1 looks like it was meant to be there under the hood-Paul you should post some pics.

The injectors I am running are 02 ZO6 injectors, I don't know why they are maxed out but even if I lean her out a bit I don't think 95% duty cycle will be any safer..

That car looks very nice. Not something you see everyday. Arun, it's Chad from Windsor. I'm just waiting on pushrods. Everything else is pretty much together so I'll be contacting you soon.

Budget heads.... I always liked TEA's better than AFR's or TSP's or whatever. Of course the stage 2's would have been even better. Nice numbers. Will be even better with new injectors!

Guys the pics don't even do this car justice. I have always been a big fan of the last generation RX7. Paul did an amazing job-everyhting fits so perfect. The car has very nice roll cage on the inside too. It just shows what can be achieved when you take pride in your work. Myself and my buddies were in awe when we saw the car. The beauty of it all is the thing only weighs 2800lbs fully dressed!

that body style was ahead of its time when they came out with it. i remember being a freshmen in high school when that car came out. The first time i saw it, an engineer, older guy that lived down the street, ripped around my corner and was tearing *** to his house in it, black on black, black limo tint. i thought it was a modern day bat mobil. Still one of my all time favorite cars, i would take that over any other japanese import made. Adding the LS1 gives it unbeatable combination of performance and style!

Your not gonna find too many in a desirable %.
Our injectors get maxed out all the time. It doesn't mean one cannot perform at such high output from the injectors . . . but repeated back to back WOT'S will cause the a/f to go lean when over-taxing the injectors.
