they did my 500 efi computers back in 1999/2000. the boat ran and ran for more years than i could keep up with (the boat).

1 yr after selling the boat, the guy i sold it to called..... just to say how pleased he was with the boat and motors. ----- needless to say, when i saw him come up on my called id, i anticipated a whole different conversation! LOL...... i had no idea what he may have done to the boat, but figured for certain something was f'd up and he needed help!

Precision Marine does very good work, IMO.

[QUOTE=TylerCrockett;2713486]I've never had the pleasure to meet you, but you did a guy that I know's TG, previously on Lake Travis (Austin), TX. Since, it sold to another buddy whom raced (still sometimes races) it.

Haven't heard anything but good stuff about your motors/service/integrity etc......

Mark at Precision is the best around!! He is also down to earth and easy to deal with and doesn't screw you on the price!! I can't say enough good stuff about him!!!

I have heard good things about Gary Talyor at TPI performance inc. He is a Fireman and builds only fuel injection marine motors.

Oh yeah coast me two engines - Burn holes in the pistons after 5 minutes. They say they are the authority on the ECM software, I sent them all my specs for a 572 bored and stroked 500 EFI - used their injectors, Map sensor and throttle body kit - The result FAT idle, LEAN everywhere else - Nice guys but they don't have a good standing with me. It cost me about $12K in two rebuilds - you should see my brand new JE pistons after 10 minutes - NEVER MAIL ORDER an ECM for tuning - Dyno it PERIOD - then water test, plug check and do it locally

yup, dealing with them for over a year on a very bad tune for my 500 hp. def not good to deal with these guys. I sent the ecu back twice and still having issues w just getting the engine to run right

These guys built three motors for me, shipped my boat back, one motor had blown head gasket. Looked into the problem and they used too long of headbolts in all three motors. They rigged the water lines wrong and all three motors were running way to hot for blower motors. They offered NO help and said NO Warranty. Had too rebuild all three motors at Sterling. Sterling came to the lake with me and dialed them in. The boat runs great now. Sterling are the guys to build your your motors. They are a class act and also stand behind their work. I would never do any business with ASM. They are the worst company in the industry I have ever dealt with.

STAY AWAY FROM ARIZONA SPEED AND MARINE>>>>>>>>>>

Wow, w/ all the NEGATIVE reports, how R these people still in bus???????

I think they are in business cause when they started they gave a dam now not so much. Wish they could see this thread!

Bet they have, or heard about it!!!
