Do you have stock air box or any other mods that would help achieve those figures? Also is yours auto or manual. Mine is an auto like the OPOriginally Posted by mullet_hunter

When my car was getting chip-dynoed, the bloke there told me something I didn't know. The limp mode is caused by a number of factors creating a certain "scenario" when it comes to air/fuel/boost/temperature side of sensors...

Yeah with the hpd maf housing and air box lid you can have as much boost as you want.

Still got the limp issue after numerous tweaks. Problem might be elsewhere I think. Would getting a dyno tune fix it?
A dyno is a waste of money, unless the person doing the dyno knows how to adjust these valves, and I'm yet to find one. Not saying there isn't...Lol
So. Whats your max boost level? Does limp kick in at anytime your put the boot in or just on certain hills or ways you drive? Have you given the MAF a clean lately?
I will add, prior to me getting the HPD maf housing, I could not get anything over 16psi. And even at that I had to have a fairly slow spool up rate so I wouldn't see limp mode. It wasn't the maf as I had changed it over with no difference.
So what I'm saying is, some ZD30's just don't like boost. Drop your max boost a tad, so if your at 16psi, try and drop it by half or quarter a psi if you can. Then bring the spool up rate back up(winding in the needle valve).

Thanks mudski for the advice. I changed the maf on the weekend. The one I bought from you before xmas. I will take your advice and do the adjustments you advise. I will try it over the weekend and see whay happens. Thanks again
Well my saga is continuing. I have got rid on one point that it goes to limp at around 3200 rpm so it is getting closer to being gone a few more tweets and it should be solved. Thanks for all the advice. I will report when the problem is completely solved. Thanks again
