Ok, I have another ATP GTX30 in my hands at the moment, its WGA part #480009-6 which is apparently 14psi, appears to be a common part number. Take that info with a grain of salt

I have the catted cp-e dp, Im hoping when the time comes that the boost is raised that creep is less of a problem but not overly confident on that! I did port the WG but after seeing just how much some are removing in MSF that I may have to attack that again.

Small late update, I had some spare time so I fitted a boost gauge, refitted ATP boost hose with the hose barb fitting and removed my boost signal source from TMIC tank. Pretty sure that my fitting into the TMIC tank was the issue, the protrusion of the fitting on the inside must have been in the ai...

I did have one of the other tunes in it but decided that I would leave stock with the changes being maf and sensor related until I my head around all the avenues, wasnt sure how things would pan out with all the work in the engine haha

I have no drama introducing the EBCS back into the system once im happy that WGA is doing its job, meth/E85 may be a later addition but at this stage the idea of this car is mainly to pull up, fill it up with 98 as always and then drive it after all its a street car. No changes have been made to the...

My block is built but also has alot of money invested in it so not keen on stuffing it up!

Thanks for your comments!

I was told there was a 1950 relief valve availble? Is there no advantage of trying this or does FRP become uncontrollable above your suggested commanded FRP?

You know your way around VT well! love your work!

So once you hit the limit where inj DC is no longer effected by raising FRP and providing you dont hit the 2050psi max everything should be fine? Do you limit your inj DC to a few % less than 100% for safety margine? Just getting around all the principles before I change anything! Still havent done ...

Will raising your FRP effect your inj DC (lower it) or are you at the point where the injector just doesnt play the game and there is no point in raising FRP?
