Neon srt4 issue

[jfresh]

So I bought the Diablosport trinity because I heard it would help eliminate some of the lights I've been getting on my 03 neon srt4. I have a agp wastegate and bought the 8lb spring which is equal to the stock wastegate and hooked it back up to pcm controlled boost. I lost about 2lbs of boost by doing this but I figured I'd prefer the tune so I had to. Now was driving today really testing it out with the tune and it was great I felt the difference. Perfectly fine at high speeds and what not then I'm cruising at about 75 and boom here comes the light again so I checked it and it was the p1188 which I've been getting for about a month now. I used to occasionally get the p0234 which was an overboost code but that seems to be gone but the p1188 is what trips almost every time I drive it. It always happens when I'm cruising and there's just a little bit of boost for a couple seconds. I know what the light is but I can't seem to keep it off, just when I think I've fixed it there it is again. Help and suggestions would be much appreciated.

Also I replaced the tip sensor so it's not that and I've checked all my vac lines and I don't find a leak anywhere so I'm lost now.

I guess no one knows

I have an 04 srt-4 and put the Diablo 93 tune on it and now it won't go over 10lbs of boost. Can anyone tell me why? And I have an aem wide band but it always reads lean unless it's when I first start it up. I'm new to the srt-4 so please help

everything under hood stock?
all vacuum lines routed properly?

Yeah pretty sure no one knows on this forum more than none.

Yes everything but the cold air intake and exhaust. I ended up taking a loss and letting the car go cheap because problem got worse and worse. Turns out that the Diablo program had my fuel system 2 lean and it would boost/fuel cut thinking it wasn't getting the proper amount of a/f mixture (it wasnt) so with this being said and about 3k out of my pocket I would recommend that you tell your current and future customers that a stage 2 ecu and or bigger injectors are a pretty much must have. That or go back and do some tweaking on your 93 tune and add some fuel. This was told to me straight from the techs at mopar. They say they see more and more of these problems everyday. People buy a product from Diablo sport thinking they can just set it up and load a tune off of it onto their stock ecu and it ends up leaning the system out and/or multiple other problems. Definitely not a "plug and play" design. Any help on this one? How about shedding some light on the subject even though I'm out of a motor, turbo, and ecu. That's where the 3 grand comes into play. Can I get a reply? Some credits, products, or at least a reply would be nice.

These tunes have been out for years, and are incredibly popular in the SRT4 world, weve sold almost as many srt4 tuners as there are SRT4 Neons in existence. Many of these cars do require custom tuning but to say an S2 set up is required is far from the case. I have seen properly tuned stock pcms support over 650 whp.

Thanks
