3.3TT Supporting Mods for JB4 MAP 2/3

so you technically dont need boostane to run map 3? just 93 and gapped plugs from what i am understanding. and other mods dont dictate the mapping. its actually fuel quality?

What plugs are the best for running Map 2?

Has anyone used NGK R7437-8. They're "racing" plugs, but I'm not sure exactly what that means, and the marketing around them doesn't help clarify it either. @Toddasaurus did a pretty in-depth analysis of the various plugs available for the platform on the G70 forum, and these seemed most like the OEM plugs in a cooler temperature. They are really expensive.
 
Members who have used them are finding that they don't last long and need to be replaced way before the claimed 40k miles.
A quick search on Denso's on this forum will get you the info you seek.

So HKS M45iL is the way to go for JB4 MAP 2......thanks for heads-up on Densos

We have a nice gapping tool on our site as part of a package with the plugs. :)
 
Boostane is great . Used it a lot with my stinger over last 3 years. One thing , it will kill your spark plugs way early and you will get bad misfires . Just have a new set around if you use boostane or torch. And it leaves everything orange inside engine . So if it blows they will know and void warranty just a heads up. Have fun

I regapped my stock plugs to .025(had jb4 readily available and had to wait on plugs) along with an injen cai only so far and ran maps 1-4 with 3 gallons of e85 on a full tank with good feel throughout. I have HKS plugs otw but will probably run more logs on the stock plugs before swapping them out so I can run some very similar logs between the two and maybe find some key diffs. I was told not to run map 4 but of course I did, power is power and we’re all little junkies so yes it runs just fine. Had Terry, who is awesome btw, take a look at my logs in map4 and he said they look fine (tip for anyone else new to logs- make sure you run wot long enough to get a solid log worth reading, otherwise it’s just a lot of spiking) **Just make sure you buy the gapping tool from bms or else you’ll hate regapping your stocks... it’ll take longer than it should and be annoying**

Hey guys I need a little help with my JB4 logs, for some reason my Target seems way low regardless which map I’m using. I’ve attached 3 logs with the WOT timing in the title. I’m still learning how to read the logs better but it also looks like my ign is a little more volatile than it should be but I could be completely wrong. FYI I re-gapped my stock plugs to .025 and am installing HKS plugs at the end of the month but haven’t had any codes, chokes, strange idles with the stock plugs it’s ran smooth. I can feel the power without a doubt with the Jb4, especially moving up a map but want to make sure it’s running correctly. Also the two most recent runs are on a full tank of 3 gallons of E90 and the rest 93 octane. I appreciate the help and hopefully the king himself Terry can take a look if he has time A90D3CCB-8953-4A12-9546-EBD4FC2503BF.webp98C8FED3-6101-4963-A524-3B62E28D21DC.webp

At quick glance your photos seem fine. Target is boost requested over factory.
Thank you so much Terry, we all rely on each other’s input and yours carries a ton of weight with it. You’re the backbone to running JB4s. My ignition was worrying me since I just re-gapped my stock plugs instead of replacing them. Do you think I should still replace them with HKS or since my car is running smoothly just stick with the OEMS? Someone on here said you get a minor hp bump upgrading but I’d rather run smooth and clean which I am after re-gapping and I’ve ran up to Map 4 smoothly.
 
My 0.02 cents worth.......Once you leave MAP 1, regardless of fuel enhancement, the old "tuner's" oath comes into play......" leave extra HP on the table for the sake of SAFETY"......i would back off until the plugs were replaced.......even with the good looking runs, BAD things can still happen.
