My New Numbers
Last year I was running bone stock 03 gpr at 63.9 on GPS.
Over the winter season I put on the following mods:
Jim's FF plate (no holes filled yet)
head milled 150 psi
Solas 13/19 concorde
protec reed stuffers
R&D Plenum F/A
waveeaters clips and couplers
2 weeks ago I ran 71.8 and 71.4 consistantly. I haven't been able to tune much but I did take the pump back off today to remove the small cone in front of the impeller and re-yamabond the pump. I then changed the plate's shims b/c I suspected drag. I had J-gapped plugs that installed and also indexed them with my kit I got last week. Today I was in a crunch for time as it has been raining on and off for the whole day. I decided to try and make it out for a couple runs. at 897ft 75* 87% humidity I ran at 74.8 mph GPS then 74.5 on my second run. didn't have time for any more. I haven't tweaked my EFI much more than 20 minutes worth. haven't found the sweetspot there yet.
First off I'd like to thank SpeedJunky(kevin) for helping recommend mods that would help me... He's answered so many questions (newbie/annoying ones) and helped a lot. Also thanks to Carl at IR and Jim for helping me as well, both have answered multiple phone calls from me. Thanks to everyone for your help.
I'm not content yet. How much more speed is expected from tweaking the EFI? I guess its hard to tell I could have it dead on but that is unlikely. I feel like I'm running rich but don't want to lean her out too much. Is there a kit for removing trim tabs? I suppose you'd want to fill the holes up with a bolt or something yet I want to be able to install them if my results aren't good.
Is there a hidden post on tweaking the EFI? search shows nothing.
Thanks EVERYONE and thanks to greenhulk.net for existing.

Those are great #s Ben! Especially with the old style pump.
Give WFO a ring, he seems to have the EFI thing figured out.

i never got RPM readings I got my PET from watcon when I got the index kit. I need to buy wire and get it set up and I'll be able to get a good reading. I may send my prop to carl as I dont' have a prop measuring tool. thanks guys.

that is awesome! you picked up 3 MPH from removing the cone and indexing the plugs??

the plugs I put in were J gapped and it idled very smoothly. I'm very happy with the idle and I think it may have helped some on top end.
but I did change the angle of the plate slightly. I might have had drag on one front corner of the plate but I'm not sure. I'm leaving the plate where it is for now.
that thread really helps RX951. thank you
