Ok so I just had my car tuned by chad@modified by kc aka mkc and only put down 297 awhp and 305 awtq on a dynojet at 26-27psi. I have an Evo 9 with 31k and these mods:
ETS 3 inch thick core wide tank fmic and hardpipes
Buschur high boost wga
Perrin mbc
Vibrant intake
Turbo xs 3 inch downpipe with full 3 inch custom exhaust and magnaflow muffler
Pte 780cc injectors
Walbro 255 fuel pump
Works aperture tb shaft seals

Car was tuned at 11.3 afr and boost started falling to 19-20 at 4500 rpm. Turbo is good, no boost leaks, and wga arm is adjusted all the way so it should be holding around 23psi according to BR. Any insight as to what is going on would be great. Thanks for any help guys

P.s. The base pull on stock tune with wga set at 20psi put down 267awhp and 222awtq

 

what gear was the tune done in?..I'm betting 3rd gear. those #'s are low for a 9 with no boost leaks on a DJ.

 

Yeah the pull was done in 3rd gear

 

damn.. u did have 80lbs of torque increase... but its still low...

 

The one thing you didn't mention is timing. That can make or break your tune.

 

I don't think thats too bad. You really don't have much in the way of power adders. You have a good foundation. It's breathing better and is getting plenty of fuel. Now you can take advantage of that by getting some cams. I would expect you to pick up 30-40 more hp with a good set of cams.

 

yup get cams or adjust the timing with the mivec

 

using a testpipe?

 

There's no cat on it

 

Didn't know you got your tune today, greg. What wideband did you end up going with? We will have to get a few runs in to see how she stacks up to me now.

 

Thats some pretty weak power IMO.

Something isn't right if you are only holding 19-20 psi at 4500 rpm's.

If you have a friend with a tactrix cable have him pull the tune and post the maps up.

 

How about you read the rules first before suggesting someone commit a bannable offense? Such as the rule against posting vendor maps. Unless you want to take the fall for this guy then go ahead...

 

Something is definitely wrong. I made the same power on a dynojet with less mods and a stock boost tune.

 

I wasn't aware they were a vendor on here.

Wasn't suggesting he go get banned over a bad tune...

 

Yeah im thinking either my mbc or wga isn't working properly. After talking to BR today it sounds more like my wga but I was also told today by a reputable tuner that the Perrin mbcs are junk so it might even be both.
