Did they do a baseline run of Ur bike??? Without one U don't really know what U gained or didn't gain.
A dyno turn is just a tool to make Ur bike run better.
The numbers Ur get can vary all over the place pending on Who, How, When and Where its done.
Don't get too hung up on the No's. No two dyno's will produce the same No's.
First, can U feel the difference,?? does U bike start and run better.?? Did Ur Oil temp drop.??? Are U getting better fuel mileage.??? All of these should happen when U add cams and get a good tune.
As far as the seven Hrs labor. If they knew what they were doing, U should have gotten a GREAT tune.
How many runs did they make during the tune,???
Our tuner who' been tuning for 25 yrs and has done thousands of tunes with the SE tuners can do a really good full tune in 2 -3 hrs.
Also who ever told U that the 37's is the biggest cam U can install is wrong.
Lots of other cams have more lift and are still a bolt in.
Really, U don't want just the biggest cams, U want a cam to match U motor build and Ur style of riding. Big difference in choosing the right one and the biggest one.

I agree with the poster that said you really should have checked for improvement on the drag strip AND you should have taken a baseline somewhere back along the way using the same guy and the same dyno.
Having said that I am not a fan of the 37 unless you know about compression, possible headwork upgrades and fooling around with advancing the cam timing using this cam.
Most guys like you that have a stock 88B and don't want anything but to get rid of the EPA stupid cam simply opt for the SE 204 (for HP) or the SE203 (for torque).
Somebody tell me here if I have given out BS advice but that's my story and I'm sticking to it until better brains persuade me otherwise...

I wound have stuck the 26s in that 88 ci wound have done better,I run the 37s in one of my 103 @ 10:1 comp with a good tune they do better with more comp. than stock comp. you cound advance the 37s a bit so it close the intake valves sooner that wound help you some or dig in alittle more,Just sayin

The 37's max out @ 10:1 compression, then it can be a ping monster.
My bike, 98" 37's 10:1 with head work and other mods, made 111 tq and 108 hp with 105 tq @ 2500rpm. There's somthing not quite right with your tune maybe?? They do work better with more CI though, I have a friend with a 103 and he put the 37's in it, and it runs good too.
Mine is tuned right to the the edge of pinging, if it starts to get carboned up you can make it ping. I run Amsoil fuel treatment through it once a month and no issues.
FWIW.

I gained 5 hp and about 3 lbs torque. The bike does run better and does not have the flat spots it had before. The cam I put in was a torque cam for a touring bike and what I meant by biggest is that more cam would require more mods like higher compression. I am aware you can bolt in much larger cams but this is the one Andrews recommended for my set up. The only thing I am disappointed with are the numbers. The tuner even said he was surprised with the numbers, he thought he should have gotten more out it.
