Sending my ecu to be tuned by Texas speed for a 4l80e swap. Sent it once and it won't hardly run and threw 3 codes that indicate the segment swap wasn't done right. What other info do I need to tell them before I send it off again? 3000-3200 stall circle d converter. Stock 4l80e with tci shift kit

 

Ive been there ive done that, buy hp tuners and do the easy stuff yourself or at least that way u can send files and not the whole ecu

 

what did you do to fix it? i really don't have 700$ at this point. lol

 

Well I bought hp tuners. What did you do to fix it?
