I'm doing some research on a tuner for the 335i. I have looked and looked I'm trying not to but there is just so much information.

I'll be thinking I want this tuner then look up another and decide I want that. I was first thinking JB4 because its cheep and good results. Then I got hooked on Procede V5 but as usual I started to find cons and it costing more. I don't know which is best so I figured I'll just ask what people are running.

What kind of tuner and type?
What hp gains did you get from it?
Pro and Cons to your tuner?
And how much did it cost?

P.S. Also if the money wasn't an option which do you think is the best for results and integrity?

I have looked at that but I was just trying to focus just on the tuner itself. I'm trying to get away from all the variables of different exhaust, downpipes, DCI, Intercooler...ect.

I just want to know peoples personal experience with there tuners. What they would change if they could or why they like that one so much? Why did they get that one over others or did they wish they would of got a different one?

You will be around 340whp with just a tune. And its a tune, not a tuner, a tuner is one who creates the tune.

Kk gotcha tune. I do wonder though, why on procedetuning.com do they say 380? When you get about 320-330 from what I have seen on some dyno sheets.

[jdbretz]

380 bhp is measured at the crank. 330ish is at the wheels after drivetrain loss etc. As shown on the dyno

[venom3469]

I have actually always wondered if BHP was crank or RWHP. I guess I should of put two and two together.

[MKE_M3]

for a rear wheel drive 335i, you can assume about 12% drive train loss (max). The math to convert from RWHP to Crank HP is...
CrankHP = RWHP/(1-DriveTrainLoss)
example 1
330/(1-12%) = 375HP
example 2 (with Vishnu's PWM Meth kit)
Stock Map, with DCI 284/(1-12%) = 322 CrankHP
Vishnu PWM Meth Kit and DCI = 406/(1-12%) = 461 CrankHP

so Shiv's advertised 122HP gain is actually 139 at the crank

I know that you loose Hp from crank to wheels.. I just didn't know the BHP meant Crank or Wheel HP.

Also only 12% loss that seems kinda low?

Fast and furious was actually pretty good.

Let me know if you need any help. It can be very tough getting straight answers these days as this topic has been beaten to death for about 4 years now LOL

I figured it had been, I have only been on these forum for 2 days now.

I kinda put it up to soon but I was very eager to find information...I have been knee deep in this forum and others trying to figure out which way I want to start out.

So may options....like turbo upgrade, meth, tune, FMIC, DCT, Nitrous, downpipes,...excreta..plus the different setups within all those.

But thanks for the help I'm sure I will have plenty of questions in the future when I start to actually put it all together.

[venom3469]

Think I have decided to go with the JB4 tune though.
It seems to put out great power and the cheapest tune with all the bells and whistles.

You should probably do some more research...

Haha sounds good 'll probably change my mind like 2 or 3 more times anyway.

If you don't mind me asking why do you say that though?
