Also Cali.. the electronics in those cars were made so you couldnt use a grainger or other boost controls. Its not as basic as the older TDs. Garry McKissick (one of the big engine designers of the SRT4) told us back a few yrs ago that it'll be hard to fool the ECU with its much more advanced programs and many different points of retrieving info. Yeah, you might be getting the boost up a little more... but look how its running!
It also might be the computer fighting the engine's responses to the MBC since it works on TQ goals, not max boost levels
dunno..
Your point about fooling the ECU is very correct. When I pulled in I had the mod on, and I removed if for the 1st couple pulls, then John told me it wasnt making past 12PSI.
The reason was , bc I had the car running higher boost, the ECU was trying to drop it to what it *should be*, and by me taking the mod off...if droped back fomr 15 to 12. Once I reset the ECU, it came right back to 15.
Trust me when I say I am the least bit worried about the 930 look alike pull. All I need is an hour or two and it will be all sorted out.
I just had to make sure, my car would take mods, bc there is one other guy who will not make anyting above 215HP, 12PSI or 17PSI
.
With my original problems, I just need to be confident all is well.
Billy, I be coming for u soon
