You may know your motor stuff and I don't mean any disrespect, but I just think that is a little crazy.

If it lowers after sitting for a bit, your still too rich. Lean it and close the idle gap. HSN is tuned on the track. My box tune temps are always around 150-160 is all, dont worry about it, get it good and warm on the box before your qual and make a hot lap or too strapped up and have your pit guy creep in the HSN on the first stop and when you top off for the heat, shouldnt take more than a couple trips to the pits to nail it. Dont panic if it doesnt come in above 200... by the end of the heat it most likely will even rich because you'll be wide open everywhere because it wont "clean out". Club races are timed practice, get it close and finish the tune next heat.

Lean bogs are 99% of the time the HSN too lean, even if you run a super lean LSN it will still accelerate very well with a rich HSN. Tuning is very simple using this method. Your engine will love you and run much cooler than your buddies fat LSN/lean HSN and be just as fast. If your smooth on the gas in the infoeld this tuneup will get you good runtimes and alot of "pop" without getting any deeper than about half throttle on the trigger. Most tracks I race on I dont hit full throttle but a couple times per lap, keeping the HSN needle closed more will increase your fuel mileage a ton.

Rule #1 the idle should never drop lower and lower and lower EVER. If it does lean the LSN and close the idle gap to get a nice low solid idle.

Rule #2 If it bogs or gets hot ALWAYS open the HSN first and start over

This is how I tune anyones engine they bring to me, Tmaxx or Speed doesnt matter.
