Number 4 is the last piston to get fuel in the rail system. Pump hiccups or injector don't spray just right and we already have it on the edge with idc's............Boom. Or in internet forum terms..... Fail and maybe Epic Fail.

This happened to us in Texas this weekend too. The 2.8" made more HP than the 2.7" pulleys.
And also proves why here in Arizona the 2.8" can run 13.4 in the quarter, and the 2.7" has only been running 13.8. They don't heat up as much, and you get nearly the same amount of boost.

Well have fun pushing the **** out of those 42s and maybe blowing up your motor. I just cant figure out for the life out me WHY you people want to risk blowing up your motors for $230. It just seems stupid!!!!! If you want to stay with the 42s then dont drop pulley sizes. Leave the stage 2 pulley on and thats it. You can max out the stage 2 42 pound injectors with the stage 2 pulley if tuned correctly.

both of our cars took a **** when adding a catless dp on or the brand new ark exhaust....
we were both on gm stage 2 tune maybe that was where the problem was idk. i really don't think ether of us are breaking or above 250 to the wheels and i don't think if ur under that you need an after market exhaust. hey what do i know i just know for his car or mine and after market exhaust where we are at right now is a NO NO

Until then they only mean something to each owner . It's a tool to see if your gaining or losing power as you tune or add parts , NOT a benchmark for all other cars to be compared to.

If everyone used the same exact dyno , in the same conditions then all these numbers would actually mean something .
