An enthusiast with the Dinan flash may just have to get more accustomed to digging deep into the throttle if the wants to experience the extra push. Not exactly a horrible thing. Some may even prefer it this way. While others won't. It's up to the end user to see what his/her preference is. shiv |

According to the graph the Dinan makes significiantly more HP and TQ above 5500 rpm than stock.

It didn't make sense to me that Dinan's program would be jerky. I had the Dinan software in my e46 M3. It was already on the car when I purchased it and even though it gave no more power the drivability of the car was outstanding. Later on, I wanted to try another program so I had BMW put the stock program back on the car. When I left the dealer it was very noticable with the difference between Dinan and stock. I ended up going with a Powerchips flash.

What I *did* notice was that my average MPG dropped from about 19mpg to about 15-16mpg. Can someone explain or provide a link to what changed with this update?

My gas milage was up on v26 software but back down of v27 in less than 1 mile. I can't give you link because it not listed but also changed my transmission and brake assist behavior just as much. Orb |

No it doesn't, look again. It achieves more at its peak, and more at the beginning, but not more on the back end. Why?

Ok, I am a f**king idiot, you're right ([me][me]). But, notice the Dinan torque curve dives harder down after about 3,500 or so rpms......why????

pure guess......the high rpms ranges are pushing the efficiency range of the stock turbo's, especially when you up the boost w/ a tune.

I think that is a good guess, after all the car is constrained by the size of the turbos. OP: What gear did you do the pulls?

That's why you are here, to find the limit of these turbos. Shiv, I admired how objective you have been in this thread. As we now all know, Dyno's read differently, however the OP had a 51+ WHP gain from stock. So if we took Helix's results from their stock car which put out 283 whp stock, we are looking at 334 WHP assuming the gain is consistent at 51 WHP, so total WHP is irrelevant, what we are interested in seeing is total change in WHP, please correct me if I am wrong. At a max boost of 13.2 psi one can't short change the result of ~50+ WHP.

thanks for the info, you did what i didn't which was provide a baseline. Let us know how the car feels after you put some miles with the flash. Do most stock 335i's dyno at 265? So this Dyno was done on the SoCal Dynojet you use? I thought the OP was from VA?

No argument here Shiv. I think you misunderstood my post. All I am saying is you get ~50 whp from the Dinan Flash. Do most stock 335i's dyno at 265?
