i have added K&N sctx2 tune here is the dyno numbers racers edge tuning Downey calif 562-445-7001 I can`t post dyno sheet how do you do it before tune with K&n Max hp 282.42 Max torque 302.41 with tune Max hp 286.77 Max torque 311.98

 

Whay can't I see the attachments? It's not just this one, but it is all of them. Please help.

 

What octaine tune is that you are using? Your HP #'s didnt' go up much, your torque #'s look really good. I figured you would at least pick up 10-15 more HP with just the tune being added. That's my next step, tuner. Maybe on the first.

 

I would have expected more from the tuner than 4 HP, is your a manual, or auto?

Your numbers pre-tuner were good too. Was that a mustang dyno or a dynojet?

 

IT`S A 5SP 91 OCATINE TUNE THE k&n WAS ON THE CAR WHEN WE DID STOCK PULL.

 

He's getting the same results as I did with my K&N & Tuner from Doug. I gained a good 7 HP and big 13 RWTQ. Thats with 93 octane. Not much else u can get out of the K&N intake, unless some miracle happens with doug and he gets a little more play with the K&N and happens to pull out a few more ponies

 

I am very close to ordering the SCTx2 from Doug but worried that I wont see much of an improvement from my stock setup. Do you guys notice a big difference or any difference with the tune on the K&n setup? I dont want to spend 400 dollars and not enjoy the money I spent. So far both the K&N and FRPP axlebacks have given me a SOTP satisfaction.

 

Its well worth it, you def feel a seat of the pants feeling, it revs much quicker, the throttle lag is completely gone! And its always great to have when you upgrade more parts, (bigger wheels, gears, exhaust upgrades, clear trouble codes, etc.) $379 for a tuner, your def. getting your money's worth!

 

it was a dynojet i can tell you by the seat of my pant`s this is great. When they dyno my car at high rpms with thr K&N the engine was real rich 16.5 without the tune.He did the tune in 4th gear up to 125 mph wow

 

Thats odd considering Doug in his post about the K&N dyno pulls says it was running a good flat A/F ratio not too rich not too lean. That was without the tune. H/C trap in and out.

 

I think I'm going to dump my K&N air charger and get a JLT before I waste money getting my K&N tuned. The K&N gains are pathetic. I think if I clean the filter and re-oil it I should be able to get $150 for my intake. I still have the original box and everything.

 

I was trying to find the post, but I thought they were pulling about the same #'s withing 2-3 either way with all the intakes and a tune, including the K&N.

 

My plan is to go with the C&L, my shop only does predator tunes so Ill be going with the diablosport.

 

You seem to forget that the K&N probably added 15hp before the tune.. tack on another 7hp gain from a tune and you get 22hp gain CAI+tune. Thats on par with most of the other intakes.. and even if you say its 5 hp behind another one... I mean that really isnt a difference. K&N owners have come up in steps 15hp first then another 7 later. I dont see anything wrong with it at all. I certainly wouldnt plan on blowing money already spent plus more because you are craving a few more hp.

 

MM&FF test

jlt true cold air intake w/DTP tune
peak hp= 288.9 (27.9hp gain)
peak torque= 303.5 (21.5lb ft gain)

k&n aircharger w/SCT tune
peak horsepower= 282 (21hp gain)
peak torque= 300 (18lb ft gain)


That's a 7HP/3.5TQ gain. Is that worth an extra $100 to me? I don't know. I know I just spent over 500 to get 15HP out of a water pump and pullies.

Well that proves it... There is no purpose in getting rid of a K&N especially since we are talking such a small amount. The gain may sound small with a tune but its all relative to what was gained before the tune.

 

Not rich... dangerously lean!!

Anyone else have a problem running the k&n without the h/c trap? I was very impressed with the power it made with the trap out, but my rpm hand kept dancing. The car idled rough and sounded like it needed a tune up. That's why I switched to the JLT. I bought my k&n at Advanced Auto, so I'll be able to return it. I bought the k&n to run without a tune, but it didn't make enough power for me.
