You are a braver soul than I.

I predict if you push it past 18/19 psi you will run with the MAF pegged at 5v which could eventually lead to leaning out to the point that you melt a hole in your piston....all without an indication of knock.

But feel free to prove me wrong!

Well someone must find out right. I will probably just run it peaking to 19psi and tappering to like 17psi.

I tried the diode yesterday, but the guy at the electronics store gave me the wrong diode that only produced an engine light. I will try ordering one of the net and see what happens. If not I'll pick up a defencer.

Yuppers that's where I was trying to get mine or a tiny bit more and I hit cut in 4th and above randomly. Soon to be fixed though.

I am just waiting on the diode. I have found the right one when it comes in I will try that then turn her up a bit more.

Diode is in. Boost is creeping towards 19psi up high and tapers back to 18psi right away. Tapering to 15psi by Redline. Much better. Has anyone ever used a zener diode before? Make sure you ground the negative end to the body and just tap the signal wire.

Well lets say its not even comparible. I would bet an extra 60-80chp from where you are now maybe a bit less. Like leaving you in the dust different I don't know its hard to judge. I do know that when I had Rob's 440 tune I race my exact same car but stock and it was a beating.

I would recommend a TBE and a better IC for the 550 tune and this much boost. Other than those yes Phase 1 to Phase 2 injector collars, 550s and a MBC with Robs 550 tune.

It should be good. I am running a 02+ USDM TMIC on mine which is barely enough yours should be better than that.

My ECU worked like a charm this time rob your customer service it top notch and I want to thank you for your work and help on this. My car runs great now its nice having and extra 4-8 PSI of boost. before I was running like 10 PSI on Low and 13.5 on High now im running 14 on low and 17.5 on high. My best mileage to date is 21.5 but the newness of the tuning is still fun to play with. O yeah and the EVO X that I had to school is currently thinking twice before picking on a old looking cars from this point on.

THANKS AGAIN YOUR CUSTOMER SERVICE IS TOP NOTCH DO NOT KNOW WHAT ELSE TO SAY ABOUT IT!!!!!

Mine is running strong as ever. It is starting to cool down to -10 C in the mornings here and all is well also. I may turn the boost down for winter though as in the snow traction is hopeless making this much power

on the ej20G you need the collars to put in the 550CC STi injectors or those fuel rails instead of collars what ever way you chose to go with. Someone above asked the required parts list for this type of tune and he was told to use the collars but it was also being pointed out that you can just use those fuel rails instead of the collar kit

It was just totally out of left field. Noone has said anything about injectors in over a month. You updated how your tune was working for you and then there's a post about how you can use the Ej25D rails. It just seemed OT and out of place.

Collars worked great for me. You don't even need the injector clips either as ours work fine.
