106 mph traps almost full modded???

Some suggestions will help.
Iam sustaining 14.5 through the power band. It was a 60F cool night and i couldnt do better than 106mph with a 2.1 60ft on runcraps?

Map7, DCI,Muffler delete,CL downpipes.

I just replaced the spark plugs but it didnt help and also raised the duty cycle of the jb3 to no avail.

No codes , No boost leak. IAT's @ 130F at the top of 3rd.

Whats weird is that the car pulls like an animal everytime i leave the track i could hardly do a 40pull without loosing it . Also i could put about 2cl's on a 110-111 mph car.

You might want to get an actual exhaust....a muffler delete may sound ok but no one has actually proven any gains (at least to my knowledge). At most you're saving weight...

What about a FMIC? Or meth injection? You're no where near fully modded.

I had the same thing happening to me in my evo. Turned out to be my clutch was slipping under heavy load. I replaced the clutch and my trap speed returned to what is use to be.

do you guys have the preset global settings. What are the preset global settings supposed to be at. Chris- Don looked at my global setting and my Taper was at 46 and switched it to 58, But the car was slower? although on the way home the car was pulling great.

You mentioned you're getting VANOS codes on the other forum? Probably related.

14 psi on map 7 is low, you could have a boost leak. As other have stated, you car is not right eiher way, you should be trapping at least 112 mph.

What did Donald run? If he had a low trap it could just be the track. Etown is hit or miss.

Yea I just saw it on n54. I don't understand how you guys running so slow in perfect weather. Neither of you logged for all you know the juicebox decided to run low boost cause it was cold. Good luck with that cause without logs your issues can't be revealed. I have an idea though

Idling at the track is probably not doing you any favors. On the highway your IATs will be much better with all that air flow. This could be why your car feels so good when you leave the track.
