Could give you a review and impressions once it's working right.

Won't be able to drag it on the half mile though because the last one for this year is this Sunday 😞

Please definitely let me know!!! Thanks so much!!

Did you have to send dme in and do you know what code is popping ?

[perrymaxima]

This is for the N63 or N63TU? I have read that none of the tunes work well with the N63s except JB4 with minimal power gains...

[Rob09msport]

N63 Sergey is the best but for the tu idk doesnt seem to be as many out their that have used him

You know better than anyone. I just was going iff my experience cause the n63 you have down pat but seemed like you havent done as many things with the tu cause when I was asking about the tune you had to look into few things then never got back. I do know we are in middle of pandemic and i am sure your busy. I def wasnt trying to put down your tune either I was just saying from what I have seen I know n63 their is no doubt on who to use but the tu idk. Was never saying you are not good or to not use uf you have a tu.

Do you have a flex fuel sensor installed?

can you make a log with JB4 and post it up ? i am more than sure you are losing power with that intake set up vs stock.

no, don't need it , not running full flex not even 50/50 ... i run 60 or 70 % / 91 and 40 or 30% / E85

Why are you drawing in air from 2 different locations? The tube at the front and the filters?

i am running JB4 stage ll with NSRF DP's and it's ok as far as performance goes... i don't have any check engine lights or anything but if you want real power you have to get a flash tune . I haven't done that yet because I can't find anyone local in Los Angels who will do it for a decent price and I'm not too crazy about sending out my DME to get tuned .. i never had the stage 1 so i can't tell you the difference but i did have the race chip and i'll choose JB4 any day over the racechip gts!!!

I tried running a different setup at first with the filters in front behind the grill but i got worried when it started to rain that it may suck in water so i ran them the way they are now , i didn't loose any power nor did i gain any ... it's mostly for the sound ... with the DP's and the intake setup the turbos sound sick

You're still sucking in a large amount of engine heated air; probably more than from the tubes.
