I bought a pair of AZSM efi packages for a pair of 502's for one of my 31' cats equipment was good , calibration was TERRIBLE ! Tyler recalibrated the ecu's and all was fine.
If you have issue's Crockett Marine engine is the place to go,
good honest guy !

and if you are close to LA or MS Mark at Precision is the other guy to go to..

AZ Speed's assembly area looks like someone's unkept garage! I am convinced that those clowns couldn't have known my MEFI unit from another. They probably just pulled mine out of a heap of junk on Monday morning, attempted to program it (for like the 4th time), and ship it while being proud that their useless service just landed them another several hundo!!:angry-smiley-055:

I have just had my ECM reprogrammed by ASM, along with flow testing the injectors. They also picked the roller cam I should use. I just became aware of this site and quite frankly, you guys have me scared to death. I'm in Wisconsin, where should I go that is local?

I cant believe someone hasnt kicked his a** and why the hell are they still doing work?

I had ASM do my engine package and tune. Everything runs great. No problems with my supercharged stroked 454 efi. I did take the boat to him, so they could put it on the dyno and tune. I sent the box back to him once to add some full. One day turna around. Always awnsers my calls and silly questions.

Thing's that make you go Hummmmm!
i just started to do a little home work where to buy a MIFI3 for my 575sci and ASM was and i say was on the short list as where to buy one.
Can Mercury reflash them or once they are screwed up they go in the deep 6??

Jim at asm built my engine...it screams...very pleased...put thirty hours on it this season! but when it comes to tuning imo u need some one that can run your boat on the lake. Hook up an o2 sensor and program while running on the lake underload especially if there are mods done......imo a lot of people get in trouble sending their units in to get programmed then they run too lean and detonate and do all kinds of nasty things to pistons and so on. I had my boat tuned by asm ...and decided to make some changes and had Paul Pfaff tune it on the lake. The boat lives in California so it was easier then taking it back to phoenix.
