Those DENSO's are definitely causing it. I could not believe they were even working at all to be honest. You are the third person to have zero luck with them in the past 60 days. I bet if you put the original stock plugs back in your car will feel a million times better..Ben's car would not boost pat 20psi with those plugs brand new, switched back to stock plugs and problem solved.

 

Thanks for a quick response. How is my v7 map coming along ?

 

I grabbed a set of those Densos for Jim, and am now returning them for the NGKs. Dont want to say that Ben was a guiney pig, but it was a good thing he tried them before Jim installed them on his car.

 

Honestly I have not touched it yet but I figured out why I was having trouble, it was definitely your map sensor scaling in ecuflash was not actually changing, even though it showed it was, if that makes any sense.. I am hoping to have it for you before the end of the weekend. I haven't been home before 11 all week and I start at 8am

 

can go wrong with NGK coppers. they're cheap work well.

 

+1 and ben was not the only one with problems either

 

evo IX guys dont have it so well I must have bought like 100 ngk coppers in my lifetime lol, never a single defect.

 

Tell us about it... Evo guys never have it easy Stockers it is

 

I am HOPING to work on my car in 2 weeks I think I am going to order all my parts next week, now I am undecided if I should just do valvespring or a spring and retainer kit.. I don't think I will gain any benefit from retainers ect. but hey, while I'm in there

 

Petey don't overkill yourself... Last week I had the same story, this week is a bit better

 

about time

 

Sounds like the S2 are on order? Why not ge tthe GSC Beehive kit that you told me to get?

 

+1

 

xpehbam did you recently go SD? I had a similar problem and maybe it's what you're experiencing as well. Plugs helped a bit but I also had to apply the mrfred XML fixes and one of them worked (don't remember which but I think it was #2). There's a weird breakup that occurs from injector pulse width dropout on the speed density rom generally around 2000-3000 RPM. I had it all through the rev range though at part throttle. It's annoying as hell trying to accelerate into traffic and getting only a sputter unless you go WOT.

 

marc, this still cracks me up
