do i need a reflash after a DP install?

 

Hi

Have you logged with your DP installed? Can you log AFRs? Was the e-flash done with all your other mods taken into account?

from what i know U could run richer. depending what is difference between DP's so better check with wideband.

 

Your sig says "tbe" so did you already have a aftermarket DP and you just switched to something else aftermarket or did you go from stock to aftermarket? If you had stock and now have something aftermarket I would most likely buy something else to warrent a reflash. Like maybe a 255pump or o2 housing or something cause chances are you wont "need" a reflash but at the same time if you dont get one then whats the point of the dp in the first place since you wont really gain anything from it like you would if you got flashed.

 

it was from stock to aftermarket DP.

 

Just log and if it needs some changes, contact Scott @ TTP for some tweaks (since he is the one that did the flash)....

 

scott from TTP sent me another map for use with DP and another job well done scott.That map you sent me works well with my TTP DP.Thanks again.TTP rocks

 

No problem.

 

ACtually, a larger, higher flow DP can actually cause a lean condition and will cause the turbo to spool up faster and reach full boost faster(from lowered backpressure), causing a lean condition. healthy trade off's after adjusting to the proper AFR is A) lowered EGT's from lowered backpressure and B) allowing for more ignition timing in boost, which in turn makes more power and allows for additional boost pressures safely as a general rule.

If you are brave and know what you are doing, you can actually increase spool time more by retarding ignition timing to raise EGT's(controlled) at the begining of the spool for a few hundered RPM then return ignition timing to the proper values in boost.
