05 Mach Z w/ Performance Mods Not Running Well

699 Views 8 Replies 7 Participants Last post by  skidoo925
I have an 05 Z w/ all the updates , 05 mapping , CS twin pipes , domes , boondocker control box , clutching , 1 1/4 rip saw w/ 192 carbide studs and i had a chance to run it on the ice this weekend. When the sled hooked up it would rip your arms off up until 80 mph and then it would take for ever to climb to 100 mph and my best speed all weekend was 112mph. If an f7 , fusion 900 or a rev 800 got out in front I could not pass them in 1500 ft. My RPM's are at 8000 and my Egt's are reading 1050 at WOT. With the work i have done I should be killing these guys. Any suggestions or help would be greatly appreciated.

No offense but you should take off all that crap and go out and drive right by any of the above mentioned sleds. An $800 port job is the best single mod I have witnessed other than nitrous.

I would try adding a little more fuel to it on top. I have the pipe and domes
but I have the tfi box on mine. runs 113 to 114 in a 1000 foot every pass on the gun.
Also what spring and ramp are you using. that can make a big difference.

I dont think he would want to add fuel with his egts at only 1050 he probably needs to take fuel away.
I heard the same thing "add some more up top" I have the same setup but refuse to ride in the grass to test it out. PM Chuck !!!!!
I HAVE THE SAME SET UP ASWELL AND RUN MY EGTS AROUND 1175 TO 1225 WOT... I WOULD THINK YOUR CLUTCHING IS THE PROBLEM, BUT JUST SPECULATING...ARE YOU RUNNING STOCK GEARS, WERE THEY???
I AM RUNNING STOCK GEARS IN THE SLED. AND I TRIED ADDING MORE FUEL ON THE BOX AND I ALSO TRIED TAKING SOME AWAY WITH THE SAME RESULTS. COULD THAT MEAN I HAVE A BAD BOX ?
