screaming eagle 103 stage 4
Just had a 103 stage 4 race kit put on my 2007 sg. I allready had a thundermax ecm on the bike. The 103 kit included the 58mm tb with high flow injectors. The bike rips unbelievable throttle response, just blipping the throttle results in a hard powerful surge of instant smooth power! Best $ 3800 I ever spent. Here is my problem the bike stumbles and pops during warm up once warm it run great althought the idle fluxuates a little. I called thundermax sent them a download of the bike and they told me that the 58mm tb was to blame for the poor cold performance stating the tb throttle plate shaft has to much play. Anyone have this set up or have a similar situation? Gregg

They are wrong. They are telling you that because they don't have a base map remotely close. I have the 58 tb and I have none of what you describe. Your bike is not tuned properly and you may be also suffering from being overcammed if you have the SE260's. I have no experience with TMax . My cams are similar to wood 777's and I have the mva heads along with the 58tb, no idle or low speed issues at all. You need to find someone to tune your bike.

I was not happy with the customer service from thundermax, it took two days for them to tell me that. I checked the throttle shaft and there is absolutly no play in it!
The stage 4 race kit came with the se 259e cams they really pull great even down at 2000 rpm but really come alive at 2500, if Im in 1st or 2nd gear at this speed and wack thge throttle the wheel breaks loose! From what I have been reading on the specs between the 260 and 259 cams the 259's are more streetable.

higher cold idle speed might help.
you can use the Tmax to increase your cold idle speed....after it warms up...it would switch to the warm idle speed.....

The 259e's work just fine. The 58tb works fine. What you need is a proper tune. Its up to you how you want to go about getting one.
