Tuning??

Is there anyone with standalone ECU with low comp 7.8 comp engine???
I have track heat inlet and ported TFS heads, 236. 226 @ 50 cam 114 LSA..
I have issues with std idle control..The idle is far better left at 900 rpm..
No matter what we do it seems to have flat spot going from idle to rpm especially when cold. Which I assume is lean condition ?
I will make up a two port attachment to fit hoses where ISC goes and fit ISC from Haltech optional parts, which is a stepper 4 wire type...
I'm also having issues with fuel boiling, only on repeated dyno runs....
When it boils the pumps cavitate, they are twin 044 Bosch inline and 255 Walbro in tank.. The surge tank is over a U.S gallon...

So I'll insulate some hot parts around fuel lines...Making enough power!!! Just hoping someone has similar issues and sorted them ????
