So just an update everyone. I got my clutch weights installed yesterday with pleasing results. So far its exactly what I was hoping for. The 18g weights definitely gave be my bottom end punch back as well as the top end when I have extra passengers since putting on the 28" tires. It took all day yesterday to do it and let me tell you its not a horrible job to do but the amount of things you have to disassemble to get to the clutch is kind of a pain but worth it in the end. Sorry I didn't take pictures of the whole process but I was borrowing some good friends of mines garage to do it since we've had rain out here all week and I don't have a garage so I was just trying to work as fast as possible. I still didn't finish until about 1 am last night. We took it out for a middle of the night test session though. Im about 195 lbs andmy buddy is about 275 and it hauled us like it did with the stock tires. I was able to max out the speedo at 51 on a slight up grade on the road with the 28's. VERY NICE!!! It doesn't sound like it's over revving either at top speed. It actually sounds like I have plenty of room to go. So time for this new ECU flash now. I think its exactly what I need to finish her off and end up with the reliable extra performance I'm looking for.....
Are you concerned that if you do get a different ecu with the capability to hit 65 mph that the 18g weights will be to light?

My plans down the rode is to get a different ecu, but I also want my clutch to be planned around a higher top speed.
 
I'm getting some 19 gram weights to test with. The 21 gram weights I'm using now are just a little too heavy for my liking. 18's are actually 17.5 grams so I think 19's will be a sweet spot weight for slightly bigger tires and top end retention.
Massive are you considering the Weller racing ecu? Potentially with the added fuel 21 gram weights would work out great....
 
Looking forward to a review. I was really wanting to hold out for something like the Dynojet Power Vision. I would like to be able to adjust things myself or have it tuned locally. I just don't see that happening anytime soon. The Weller Racing ecu maybe our only option.
