TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

@12TRDTacoma what are the codes you get every once in a while when you have MAF sensor issues?

 

P0103

 

I had the P0103 code today running TRD tune with 2.6, FPR mod, & URD intake. Popped up after a long WOT run. Is this normal or something to be worried about?

Would this indicate that the MAF is starting to go bad? Havent heard any knock on mine

 

Just dug way back and found one of your posts on this..

 

I was experiencing that too. Cleared it with my ultra gauge and things were fine. Now I have new plugs, 2.5” Smoothflow, FPR mod, new lid gasket, and it hasn’t happened again. Only 30 miles since I picked it up with my new WAT valve body, but I gave it a good pull and all is fine. AFR’s are great since the gasket got replaced.

 

I have done everything you listed recently as well(minus the valve body), but it popped up today. Not too worried about it and i have another MAF as a spare just wondering if i should throw it in there. Mine has been driving great regardless of the code. AFRs are nice and stable and rich in boost. My boost is only 8lbs with the 2.6 on the TRD tune though. Not sure whats going on there, probably belt slip. I am working on that though

I cleared mine as well, and did some WOT pulls and it hasn't come back yet

 

What altitude are you at? I still don’t get the whole belt slip thing. It’s it’s slipping should be burning through belts and smelling it and belt dust everywhere’s. I’ve never had a problem with belt slip

 

2000ft above sea level. It hit 10lbs recently with the 2.6 and UCon in there. I dont think the boost #s are based on the tune you're running, so that tells me something else is causing the lower numbers like slip. I have also confirmed it slipping on my Snow boost gauge. Itll hit 8.0 then slip back to 7.2... 7.6... 8.0... 7.3... This is happening at higher RPM WOT

Thats the main reason i think it's slipping and because there is belt dust on the bracket that holds the idlers

 

Its also warmer now, so that probably has more to do with it.. I think it was in the 40s the other day when i hit a steady 10lbs. It was 68 today

 

So you reverted back from the ucon?

 

Correct - was having issues with a rough idle and decided to take the 61lb injectors out and try the 455s to isolate the problem. The UCon is flashed for the 61lb'ers and i didnt want to make Scott have to remote in to reflash it until i knew what was causing the issue

 

Oh, I’m at 600’ but the season of boost is momentarily over. 80 degF and humid. WTF?! It’s stupid Texas weather.

I do have the Steeda belt tensioner and slippage seems to have been eliminated.

 

Yeah it's like that here too, been super humid and in the high 70s. Texas just cant make it's mind up

I have the roush and the rip mod, but no extra idlers yet

 

Hard to see, but I have @Roostfactor pulley wrap and the RIP mod too.

 

Looking good! A Roostfactor idler is one of the next things on my list, just been super busy lately. Finally having some time to troubleshoot the small stuff now

Are you running the stock 3.73s or have you regeared?

 

Still on 3.73’s. Regear is definitely on the list next. 9” Ford rear end? I hate that the TRD OR doesn’t come with the locker in 2wd. I know you can do a mod, but there’s a relay and I’ve heard stories of people getting them locked and then not being able to unlock. Hmph!

 

ECGS makes a bolt in dana 60 for our trucks now. Might as well go for it! You going 4.56s?

Definitely wouldnt want to deal with the locker causing issues. That doesnt sound good

 

Yes, 4.56 FTW. I’m think the acceleration would be amazing. Not sure how bad the hwy mileage would be. It’s not very good now.

 

I’ve never experienced it either. Definitely not the altitude. I have minimal dust on my oil filter though

 

Shouldnt be bad with the auto. Yall are lucky and have a much better overdrive. The 6spd is screamin on the hwy. Mine turns 3100 RPMs at 80mph, but i have 4.10 gears and 265/65/17s. I get 12-13 around town, 14 on the hwy consistently

Before i regeared it was at about 2800rpms @80mph
