I did a shark ecu upgrade today and Im very impressed with the first impressions. After installing an intake,exhaust system and then a 15% pulley I could feel flat spots in the rev curve that I knew where lean spots in the fuel curve. I really like what MTH has to offer but like many I was concerned about the fact that the guy is on the otherside of the planet and doesnt seem to respond to emails and technical questions. Sure the shark is pricey but peace of mind isnt cheap. I still might try MTH to compare the difference but the shark so far has been a good choice and hopefully will get even better once the ECU learns my driving habits.

 

How could you feel a flat spot on JCW? That thing should be smooth like butter!

I'm thinking of getting a shark ecu as well. For me getting MTH will cost me more since I only have Mac then I need to get a new laptop, a cable and program.

 

Hey mypocketrocket dont you have a friend with a lap top?
It also looks like he has the jcw exhaust and intake not the jcw kit.

 

I see!...my mistake

All of my friends have only Mac and my work only use Mac.
