So i have an IX which i recently bought and everything was stock except for the K&N Typhoon. Since then i have put on a AEM digital boost gauge, AMS TBE with downpipe & testpipe. Up until then the car ran beautifully and pulled hard. Of course, always wanting more power, i decided to get a Hallman Pro MBC, Walbro 255 pump, and a reflash from Dynoflash. I installed the MBC myself, had the fuel pump professionally installed, and sent my ECU away all in the same day. (Dynoflash contacted me when they recieved my ECU and told me to remove the restrictor inside the intake or my car would run too rich after this tune) Soooo i recieved my ECU back, **** my pants with excitement, started the car and went for a spin. I noticed pretty quickly that the car wasnt running very smooth. It seems to be all or nothing, either i can barely make it up a hill while my BOV is fluttering like crazy or im in full boost. (still at stock boost at this point) also, in 4th gear at 4500-5000 K rpm and full boost the car starts to sputter and buck, and won't accelerate any further. It almost feels like theres not enough fuel to keep up with the air flow, but i can't really figure out what the problem is. I've bought new plugs and gapped them to .024, that did'nt do the fix. I did a boost leak test today and although i found one leak in the lower IC piping and fixed it im still having the exact same issues. Soooo im kicking myself in the *** for getting all those mods at once because now its a major pain in the *** to pin point my issue. Any input would be GREATLY appreciated as I am running out of ideas and my car is supposed to be much faster now not much slower!!! Thanks in advance for your help.

 

Would probably help if you bought (http://www.limitless.co.nz/cables/) or borrowed an OpenPort 1.3U cable and logged a set of data using EvoScan (http://limitless.co.nz/).

 

You need to get rid of that K&n Typhoon. Its terrible. Search about it.

The only typhoon it makes is a typhoon of problems

ps. not trying to talk crap or anything, just trying to help you.

 

I am aware the Typhoon sucks...like i mentioned it was on the car when i bought it I did not purchase that intake. However Al at Dynoflash told me it would work fine if I had the metal flap/restrictor removed which i did. Plus now I am already tuned for the Typhoon so as of now I am stuck with it. I do not believe the Typhoon is the cause of all these sudden problems. Any other suggestions would be appreciated.

 

I know it was on the car when you got it, as I read your post. I understand you didnt go out and buy it. Still it sucks.

Also, you should read around more about dynoflash and Al. search about "block tuning", Als favorite way of tuning, which is complete garbage.

Also you are not "stuck with it".

Also you may not "believe" that the typhoon is the problem, but if you can get access to a stock intake, you may wanna try it out and just make sure that the typhoon isnt the problem. You might be surprised.

 

well a dynoflash mail in tune is garbage first of all lol block tuned **** pile. get a real tune from a tuner that is your main problem

 

I live in Idaho, there isnt even a AWD dyno anywhere near where i live, nor a tuner for 100's of miles.....

 

But you can do a custom E-flash over th net, though email. PM me and ill tell you about them.

 

UPDATE:

Turns out the solution to my problem was of course very simple. I was running way way too rich (100 miles on a tank of 93) because i was only boosting at stock levels and with my reflash from dynoflash i should have had my boost turned up. So i turned my boost up where it is supposed to be and my problem was resolved. I am now boosting 24 psi

 

Well a couple things. glad you got your problem fixed.

But gas mileage doesnt relate to WOT richness, as when the car is cruising the ECU just maintains a 14.7 AFR. And tuners (dynoflash included) dont tune or mess with the cruising part of the fuel map.
