I need a custom tune, and I try with my best effort but I only reach 380Whp in map 6 ... who can help me please? jb4,backend and flash, downppe,chargppe, stock turbo, waterM, oil catch can, alpina flash, afe power intake,

[LessIsMore]

So you're asking for a custom tune to help you get to 470whp? Try user trebila (David Trebila) - he can hook up a custom tune.

[THE BEAST]

You need more than tune only.

[LessIsMore]

True. OP, you don't have an upgraded LPFP or any supplemental fuel delivery method (TBI/PI/WMI). Both of which would probably be needed to get to 470 whp on stock turbos. A larger FMIC would help too.

(Assuming this is N54 since OP did not include that basic info.)

[Vorsprung_CJB]

You'll need inlets for sure, and the octane and fueling to match.

I would think low 400's should be doable with meth.

[Terry @ BMS]

It's doable but everything has to be in tip-top shape for it and inlets required. 450whp is more realistic IMHO. You can almost do that with JB4 map7, E85 BEF, and maybe just add 1psi across the board over what map7 is set for.

We try in all ways and we can not do it, give us the tricks, I'm running LPFP fuel it stage 2 with e85

[mafia321]

and fbo fmic , tmap 3.5 .. sorry

[Terry @ BMS]

Let's see your highest dyno log for starters!

I was running e85 40% I think my custom tuned is wrong ... do you have any that you can try?

[Vorsprung_CJB]

Completely unrealistic boost target. Not sure if it is your map 6 values or the high duty bias you dialed in.

What back end flash are you running?

[THE BEAST]

Wgdc is pretty maxed out. Playing with vanos may yield some positive results though

custom tune ftw!!! check my sig. thats without 7inch ic. thats going in soon with pi and a new tune. lets see if i can crack 500 again. thats on a dyno jet btw

What were the mods & psi that got you 502whp with stock turbos?

FBO @ 18psi usually gets around 400; FBO+LPFP+E85@19.5psi usually gets 450.

Rumor has it stock turbos run out of 'puff' at about 24psi, and you run into HPFP issues.

So what where you running to do 502psi?

ok inlets and outlets. all other bolt ons. it probably helps my dyno numbers that i have a twindisc..lsd 3.46. and mfactory axles. stage 2 pump e60gas. wedge tuned

What was the correction factor? Something like 1.1 ?

So what does 30psi+ get me for power,

LOL

*edit
@ Terry, why is data zap blocked?
/edit



OP,
Don't get hung up on dyno numbers. They are for internet bragging only. Get out and let the car do work. Experience matters much more than sheer power.
I've raced plenty of more powerful cars and beat most all of them. I know my car fairly well while they just push the peddle and pray. If racing where simply pushing a peddle everyone would be good at it.

Hahaha, I've never been able to calculate power from datazap logs; but from my extensive armchair internet research, 30psi on stock turbos very quickly gets you new turbos

Or, 30psi gives you an awesome youtube channel where you show off your 850whp monster with a turbo that eats birds and mickey Thompson tires that can't hold grip at 130mph...

But I couldn't agree more with your second point. At the end of the day you need something that's drivable and fun. There's no point having something with 10 seconds of turbo lag, about 1,000rpm of power band, more wheelspin than a combination lock and the handling characteristics of a cut snake - unless you're really, really into drag racing.

Personally, I went all out to maximize my power running E85, but almost always now just run pure gas (which makes 50whp less than E60 mix) because it's such a pain to keep driving miles out of my way to get E85, the fuel economy is ****, and around town there's practically no difference in entertainment value between driving a car with 380whp as there is driving one with 435whp.
