dyno numbers are just that, numbers.
Take it to the track and get a 1/4 ET and more importantly MPH. It will be far more meaningful...and fun

Have u forgotten that ur diff gearing isnt 1:1?

I have also had more success in recent times in 3rd, as opposed to readings of up to 15RWKW less in 2nd!

Remember the higher gear does have more rear wheel torque, but it has proportionatly less revolutions per minute which should equate to the same rear wheel power, give or take due to physics re: friction

Lol Casper (it's Krissy) you always say that. But as I've said before, not everyone takes their car's onto the track and therefore rely on their rwkw.

Timmy97EL - don't bother asking opinions on JMM stuff because as others have said, it will cause a debate. Some say it works and some have had problems. And bear in mind that some people won't tell you in a post about any problems they've had so as not to start a slagging war so my opinion, PM the people you know have had work done by JMM and find out - people tend to be a little more honest when asked in private.

Everyone will have different opinions and remember that what works on one car may not necessarily work on another. There are plenty of performance places to choose from. Speak to a few people and then ring around but don't go with a performance place because you've "heard" about their particular products or because they seem to be the most spoken about because some places have a good rep only because some people haven't spoken up! << Make sense??

My only other advice is to really take your time before spending your money! Check out a few different places - get a few opinions and then go with what feels comfortable.

I agree with memnoch ask in private and do't rush in.

Sound advice there.

I just had a look at there link. Do you know if they do work on 6's as well as v8's? 95% of the site was all talk about Holdens. Cmon the Fords

I am sure if you pay money they will do the work.

yes they do the I6 now
