I NEED HELP


My mods are as follows AMS FMIC, SS Clutch Line, Walbro Fuel Pump, Tein S tech, Defi Bf series gauges, AMS LICP, Injen UPPER Pipe with intake, Forge Unos MBC, APS 3.0 High Output exhaust, APS Dual Vent Blow off valve. Custom Road tune from Devo tuning.

 

whats is your boost set to? and do u have a flash?

 

boost leak possibly, i assume you have removed the boost restrictor pill by the selonoid? it could be a number of things but i would test for a leak first.

 

Launch better, that's an awful 60'

 

Yea I mentioned I have a devo tuning cutum road tune, boost is 25 on race gas 104

 

As mentioned a 2.1 60ft in an AWD car is just horrible. Work on that, check the drag forum for tips.

8.9 in the 1/8 is slow - as is the 13.1 in the 1/4 for your amount of boost - assuming a good tune.

How's your shifting?

 

I'd have to agree... check the for leaking and your launch. Most likely your time is quite a bit off than it should be. I can run 13.1-2 stock.

 

There's definitely something wrong with the car. It should be trapping much higher than 108mph. It should trap faster than that with just a reflash, sans mods. Could be a boost leak, old plugs, exhaust leak, crappy BOV, who knows.

 

well i think his best 60 ft was a 1.85? but still i think u could hit 1.7's and yeah check the boost leak

 

Is the clutch slipping? Take it out and boost it in 5th gear, if the RPM's skyrocket, you've found your issue.

 

I wouldn't trust a road tune. Take the car to the next dyno day at AMS.

road tunes are superior with good data logging honestly. Numbers don't mean jack, in the end it's about how the car acts on the street/strip.

 

Have you tried to tune your car on the road? It's not easy, not to mention dangerous - very difficult to get enough consistency to establish solid data to then analyze between runs (assuming you have good logging capabilities). Overall it is much easier to get a good baseline tune on a dyno. Then log how it behaves on the street/strip/track and, if necessary, you can then fine tune it.

my $.02...

First, do a boost leak test as mentioned above. Search this site for a how-to on it. Your Evo IX with those mods should be trapping around 113mph on PUMP gas.

Sure, you could work on your launch and shifting, as can everyone; however, the problem lies with your car.

Your exhaust wouldn't happen to have the silencer still on, would it?

 

this is why they have things to log any pulls dont to the car as in a 3rd gear pull or 4th gear pull and instead of being on a dyno and only doing one gear pulls you can go through all the gears log it and go back in you re flash program and fix any problems that occur you cant do so on a dyno when it comes time to make your one gear pull on a dyno get a sheat and some numbers. road tune works well
