yep, summed up well above
Service is s**t Product is overpriced I will add his dyno is VERY generous but the JMM cars do consistently get solid 1/4 mile times so the stuff does work.

who gives a f*#k what you pull on a dyno, its how quick your car your car accelerates that matters, like stockstandard said "the JMM cars do consistently get solid 1/4 mile times so the stuff does work." his got the quickest na i6 so he must be doing somthing right

JMM does, thats why he advertises RWKW on his site not 1/4 mile times. We dont get many JMM equipped cars here in SA, but two I have seen run on local dynos that I trust were well short of the JMM claims. One Dev3HL made 10rwkw less that advertised, and another made 20rwkw less than it did on the JMM dyno.

and i have seen some run 170rwkw+, and run low 14 passes.
the point i am trying to make is you modify your car to make it faster and jim mock products are proven to do that

You are right though and I totally agree with what you are saying, but its not like you cant get the same results cheaper from more friendly and helpful people elsewhere.

There stufff works good.I have seen more dyno dynamics dynos not working right and giving the right numbers than I have seen jim mock stuff not go well. The dyno figures are nothing. Why did I run a 14.7 and back to back 14.8s with a full tank of fuel ,single spinner with only 131rwkws?
I run a dev4 cam and race series extractors in standard head.

I run a dev4 cam and race series extractors in standard head. Not to mention you were running slicks, 3500rpm stall and an edit (none of which are JMM products). Didnt it take you 20 odd passes to get into the 14's after running high 15 and a few 16's. Lets also not also forget how long you spent working on that car getting it right (seemed like more than a year from when you first got the cam). How many times did you shim or clock up that cam in total? I also remember your thread where you said the cam didnt work, it took a fair few more mods before you started saying you were happy with the product. I am not trying to bag the JMM product, just not looking at them through rose coloured glasses.

There's your answer mate. Go for it. What have you got to loose? IF it doesn't work, you get your cash back. If it does, you'll be happy. While I haven't ran my car down the quarter yet, it did make 149.2rwkw with replacement headers, hi flow cat and a DEV3HL cam with the leads, plugs and intake mods. Makes me wish I had of gone the DEV5 
It's definantly a love hate relationship Ford fans have with JMM. |

I did the same mods as JMM without using him and got more power than he rates, but my car is still a slow POS, go figure. I reckon just go for it, at least you'll know the pros are working on it.

Good luck getting your money back off him... I just don't see that happening.
