well im not wanting to reinvent the wheel we have over 35k in the computers and tune but chief won't respond to requests or give us the password! Mark boos thinks he should just give us the password but he appears to hold the previous sales for Ransom. I guess its lawyer time i have too much into it to let this happen or start over! Hopefully when the word gets out he will go bankrupt and quit screwing people

He could just give you the password and a waiver....basically saying you assume all responsibility for the engines since you can not make changes to the tuneup. Sometimes guys are weird about people seeing their mapping. If its good and clean, nothing to worry about. But honestly I don't know any tuner that wants someone else mulling through their maps. Its just a thing...

My motors have NO WARRANTY and if he would let us access the rev limiter and the race tune we don't need to change anything other than rev limiter its set low at 6300 but i wanted to bup to 7k not even the 7300 they were set at before

I looked up your ECU's and they are $4,700 each. What was included in the 35k for the pair ? Wiring and sensors and install and tune ?

i guess so the most recent 4700 was to tune on Mark Boos dyno because it backfired , shifted rough and hard started . First 25k was computers sensors and original tune rest was tuning before i refreshed

Buy 2 powerboat they said it would be bud cass. Sadly this how boating bites us all. We live the sport and dump tones of money to do it. Then we get our stuff worked on and it all goes to sh*t. Hope mark can get it all worked out for you. he. Is a EFI Genius.

Old school Dominators are sure looking good right now...hopefully the added safetys of the EFI pay off.
