Guess I'll rethink the FMIC for a little I don't know about dinan but I just did a 130 run and got a HUGE boost @130 lol scared the S* outta me

Do the FMIC if funds permit 1st. Pass it by your SA if still under warranty to avoid surprises later on, if out of warrant - no worries.

Since you're not on the Dinan plan anymore, do the Helix, it seems to be well regarded.

Talk to the guys at Cobb and I think they'll agree the stock exhaust is OK for your projected HP.

Bang fer buck?

BANG FER BUCK?

Deep Six that fussy Cobb gizmo, totally unusable while engaged in vehicle primary function. Ebay a sucker, gift a neurotic person, or just donate to Cars For Kids.

Dinan? Less bang than slap to the face with a wet towel.

Now then. Bang fer buck. What Dinan & Cobb fail to grasp is: That is the domain of Methanol.

Yes. Alcohol of choice and augment of champions, both vendors are dominated and utterly humiliated simply by adding meth to your intake in proper proportion.

I'm glad to hear that you're happy with the Cobb tune. I personally have it as well in my 335i and it's not only one of my favorite mods, but it's my favorite tune that I've tried on the car! The next step would be the FMIC so that you can run the stage 1+ maps. Although an intake an exhaust isn't required, it is suggested esp. if you're planning to some of the higher performance maps available.

I'd have bought it from you guys but I'm a chepo and need coupons (says the guy that spent 1200 on stage 1)

Let me know what kind of FMICs you have I just ordered the drop in filter from BMS, I'm going to do my first attempt under the hood changing the air filter !!! I think I'll be ready to rebuild my engine once I figure out the air filter

Still found a way to mess it up (finger slipped @ like 53-54mph, but not too bad on a straight D mash

BMS drop in sounds nice

So just wanted to give you guys a quick update. I took a pic the day before I stuck the cobb on to kind of get a comparo to what the Stage 1 ran over the course of driving. So last night I snapped another of my Cobb and its kinda crazy given the vast power difference how close (and I'd say better because I'm driving more spirited with the cobb than with the Dinan)

So here is the Dinan:



21.9 MPGs @ 36.5 mph over 1831 miles


AND NOW THE COBB



21.0 MPGs @ 38mph over 1382 miles

I've dropped from the 24-29mpg ranges I'd been on stock. But I have no doubt I could bump it to 21-26 if I laid back on the spirited trials I've been doing (something I didn't get the feeling from the way throttle response was on the dinan) . This was also Stage 1 aggressive map

Actually tuned cars do pretty well. This is all inside Raleigh City limits with a high number of "its still new" pulls Current MPG at 17K miles is up 1 or 2. Had dynode 365whp at the time.

Thought you might like this unabashed JB4 Commercial First is a 335JB4 VS an Itilia. Second is Terry's 135 JB4 VS the 335 in the first vid. Best part is the last 10 seconds or so since its the "No Fly Zone" meet

http://www.youtube.com/watch?feature...&v=oDIYPW0yJ1Y

http://www.youtube.com/watch?feature...&v=ob7H0v4IfOo

Terry's record for the day was 7-0

Longboarder's supercharged M3 -- Won by 2 cars from 50mph and 1 from 40mph.
SRanch335 RB turbo 335 -- Won by 2 cars+, and almost got wiped out by a plane on the return road.
Another supercharged E92 M3 -- Won by 2 cars
Z06 Vette -- Won by 1-2 cars
Jon's 335 -- Won by several cars
Eric's C63 -- Won by several cars

Funny you posted that I got wrecked by an italia today and a GT-R even worse the night before.



Both toyed with me, like I toy with some guy with a 95 civic who just got his muffler from autozone and thinks his car is fast

The stock exhaust on the 458 is amazing.

Terry's car is quite a bit at the other end of the tuning progression from ours.

Why did you go back to stock for the IC and suspension work? Not going into to BMW are you?

Yep I would have only saved about $970 bucks going elsewhere (maybe more or less if I really shopped it around) so I figured the dealer goodwill on decent sized purchase like that is along with 2 years of unlimited milage coverage is worth that. I'd have just blown it at Nemian Marcus anyway.

Now I don't have to worry about who to complain too if there is a boost leak or something! Can't wait to run the Cobb FMIC map next week

Oh, it's a Dinan, now it makes sense to why you returned to stock levels and doing the work at BMW.
Yeah, I'm hoping they will play well together(Dinan/Cobb), as in when my 4yr/50K is up...the AP might be a strong consideration.

As for NM, 2 words for you pal....Last Call!

Oh man I've never been to that site! Does it count towards the incircle points!

I still have ways to go if I want to keep my level 4.


Oh and actually on the topic of cars.... It is hilariously slow going back to stock. I've been reading around and apparently the Stage 1 FMIC map will make a NOTICEABLE gain even over the stage1 aggressive map.
