Hi all,
Well had my XT tuned last week using the Xede piggy back which I had purchased prior to the Verso being available....We achieved a pretty good number considering the boost and mods.
Mods:
Resonatorectomy
BOMZ CAI
Silicone Turbo Inlet
VF34/P20 HPC coated
MAC 3-Port Boost Solinoid
Silicone Y-pipe & TB connector
TurboXS TMIC
TurboXS
BOV - Plumback
Xforce 3in
TBE with HPC coated Dump Pipe
HPC coated heat sheild
Walbro Fuel Pump
HKS
FPR
XEDE Piggy back
Managed 190wkw @ 15psi on DD dyno @ Xspeed
AFR's around 11.2
Wasn't a bad result but couldn't get rid of the hiccup at 102km/h (around 3200rpm).....after a bit of normal driving (ie. no WOT driving) I found it very jerky in 3rd from about 2500rpm to 3300rpm while building boost on part throttle. Felt the same in 2nd and 4th but not as harsh.
Boost wouldn't hold steady @ 17psi in the mid range also even with the 3-port which makes the mid range feel not as strong as it should.
After speaking to a few people and checking out others results after Verso tunes i've decided to ditch the Xede and get a proper Verso done as I believe I'll get a better tune for normal driving without any number fudging and hopfully it will get rid of the hiccup....the current setup is fine for FULL throttle or close to full throttle runs but seems a bit rouch for day to day driving (not to mention the missus chewing my ear off over it - main driver).
So Monday its booked in for Sean to weave his magic....I'd like to run a flat 17psi all the way which hopfully will net a few more ponies...
Anyone got any advice or things I should tell Sean prior to the tune?
Cheers
