I'm about ready to do it. I wanna contact JDM and get one of their Superchip tunes and a 4# pulley for my 03. I'm still a little concerned about long term durability/reliability but just wanted to know how satisfied you all are that have JDM's tune. I have yet to hear anything negative about JDM and am very confident in my choice to go with them. Thanks for any info/opinions. PS....is it necessary to replace the stock plugs with these mods on a 13,000 mile motor?

 

20k on the L with a 4# and JDM tune...

 

I have a 4lb lower and a superchip flipchip tuned by JDM, I just had my chip reburned and im not happy with the new tune at all, its not JDM`s fault though, I just hard to tune through the mail, so don`t worry if you need to send your chip back a few times to get it right. also, make sure you have your truck dyno`d after you add the chip and pulley to make sure your tune is safe.

 

go for it man they wont let you down. go ahead and change the plugs while your at it

 

I have had mine on for a couple of months and no problems. It sucks though, damn tires can't hook.

 

Hey Larry. You need to change your sig to show the IT22 plugs and your new Magnaflow catback. Soon to be in the 400 / 500 club.

 

I did, thanks for reminding me.

 

JDM i have had nothing but BAD luck with them

promises, promises, promises.
2 chips burned took 3 weeks &^*&*)(()^%#
1 chip had to be returned...waited 3 more weeks ..promises, promises and more bull ...

I went with JLP because a friend of mine didn't have the best customer service experience at JDM. However I had heard JDM has made leaps and bounds in customer service since then.
This board has been known to delete anything that has any unsatisfied opinion about any vendor. It seems that there is a growing trend that people are not allowed to express opinions.

 

I'm very happy with my JDM chip, had it reburned twice, and had it back in less than a week each time.

 

I've had nothing but great dealing with JDM, go figure

I also got a Superchips, flip chip for sale.........

 

That's because you're looking in the wrong place. This is
the JDM cheering section, you know ...

 

Now that's good comedy......

 

My JDM chip(J69 I think?) has been on for about 45K with no problems. It is just a tune-by-mail chip. I did dyno the L after getting the chip but it has not been "dyno-tuned". The numbers in my sig were with that chip installed; a JLP 5lb pulley, FastAir CAI, th/body, JDM cat-back, etc.
