Bigg_kayz Member 111 Member For: 10y 2m 1d Gender: Male Location: Perth, Northsider Posted 31/05/15 04:30 PM Share Posted 31/05/15 04:30 PM so I've owned my 3rd xr6t for about a week now... all utes , all 6 speeds, my previous 2 were running standard boost solenoids and were flashed tuned to 12 psi(with minor mods). The young bloke I bought this ute off went to house of powerfor his tune.. dunno if the guy down there doing the tune knew what he was doing, he couldn't work out the Greddy electronic boost controller (apparently) that was in there running an original 14psi tune, he supposedly added the boost tee to (im guessing) get past his inexperience by adding a manual boost Tee and what the previous owner told me it was set to 16 psi running 464RWHP. which is what the dyno sheet I was given showed. But on the boost guage its running 19psi with 20 psi spike , which to me is crazy!!! no traction in 1st (obviously) 2nd..3rd and forth snap sideways ... it maintains 19psi but pushing a BA MKii turbo that hard almost makes me sick .... 1)Is it too much for the car with the bottom end? 2) the guage looks to be hooked up to correct hoses, could it be reading wrong (seems accurate)? 3) is it safe to just manually turn down the boost Tee with the current tunes? can the air/ fuel mix ect get stuffed up/ do I risk doing any damage? any negative effects or can I just turn it down? any advice is helpful, cheers guys mods are: -atomic hd valve springs. -process west stage 3 cooler -Turbo smart race port bov -Brand new genuine ford lifters -Brand new Bosch 044 fuel pump and 4l surge tank -Brand new 840cc injectors. -Brand new genuine coil packs -G-reddy electronic boost controller (not used (boost Tee in place now???) (Boost is set to 16psi- supposedly, yet its running 19-20psi) -Nizpro forward facing plenum -Gt35/40 turbocharger ported and bigger wastegate and actuator -Battery relocated to tray. - 4’’ dephillipo dump, twin 3" exhaust Link to comment Share on other sites More sharing options...

Seems to have all the good stuff otherwise. Personally I'd be plumbing the factory one back in and getting it tuned properly. 20psi is a bit much on a stock BA bottom end. Depends how hard it comes in though. 1 Link to comment Share on other sites More sharing options...

Id much have the factory unit back in and tuned on an Xcal... whats the going rate for tunes in Perth when you already own an X4 flasher unit? and where would I get a factory solenoid?

Are you sure it's been removed? Common practice is to disconnect the hosing and tuck it away under the battery or fuse box. Link to comment Share on other sites More sharing options...

Bigg_kayz Member 111 Member For: 10y 2m 1d Gender: Male Location: Perth, Northsider Posted 01/06/15 04:35 AM Author Share Posted 01/06/15 04:35 AM these are the dyno sheets from a 14 psi tune and then the "16 psi tune" (which is more like 18 psi shows almost 19-20 on the guage).... I am assuming the 390 hp 14 psi tune was with the EBC , then the 464Hp 16psi tune is with the boost tee... looks like they were getting huge issues with the tappering psi at the end of the rev range on the 390 hp tune using the EBC , could this be why they went to a Boost Tee? I thought it EBC were much more reliable and stable for spiking issues? Link to comment Share on other sites More sharing options...

I have a stock solenoid which Im happy to measure the resistance of if that'll help. Link to comment Share on other sites More sharing options...

I've also seen a few cases on BA’s where the pcm was faulty so an eboost or something of the like was used instead of replacing the pcm. Which may very well be the case here. Seems odd a tuner would do this, even if they are full retard... Link to comment Share on other sites More sharing options...
