man, idk what happened to my grp. i lost all power in it. i was running 225 and was runnin so rich on the top i was gettin passed on the straight. i couldnt figure this out. i lost tons of compression in this thing. it has MAYBE 2 gallons thru it and it feels like its had 5.

i checked all over for air leaks couldnt find any. i switched to a new plug(p3) still nothing. so i let it go after messing with it all day this was last friday btw. monday night i go and mess with it again, but this time i decided to switch to a p4 plug. BAM, everything is back. the same exact tune that was runnin at 225 and was rich. went to 170 and running great.....

i didnt thing that small of a step would make that much of a difference. i was told in the beginning that the p3 may be to hot but at first it ran at 160-170 all day then at the nitro challenge all these problems started to happen. i know it wasnt just a bad plug because i changed it twice at the nitro challenge then i got i back out last friday and it got another new plug and then monday changed to a p4. i dont know what happened to the compression maybe the p3 plug was WAY hot and damaged it or just running it at 225 did the damage idk. im just glad i got the trusty grp power back

i just thought i would post this if anyone else was having issues like mine..... and btw for everyone who has people say that a grp runs good at 225. they dont know ANYTHING about grps. mines been running great since that temp change(plug change as well) and mike thrue who is sponsored by them even told me at the nitro challenge that it runs best at 160-190
