Thread: New Dyno Tune Numbers

what kind of dyno is it? dynojet isnt going to give you accurate numbers as there is no load on it.

Has anyone ever encountered this with no codes and no KR with a "tuned by scan tune" on the car. BTW:My mods:CAI,3.5"Pulley,NGK-TR6,1.8 RR,3"DP,3"Cat&3"Exhaust.Custom PCM Tune.

that's what I would have expected with your mods.......except for the torque.....maybe they started the run above 4K?

What is the stock 2001 gtp put to the wheels? That would shed a light on things considerings my mods. At least I made about 50hp or more with what I have, dont you get a 15-20 hp increase with just a cold air intake, plus I have roller rockers and the exhaust mods, so something is holding the power back.

One thing though besides the tune that comes to mind is that I swapped out all my injectors with flow-matched zzp reman'd injectors when I got my LIM gaskets done and the car became alot quicker which slowly declined since last winter. So I don't know if the they are at fault but am just weighing out the variables. There are no codes or KR as I mentioned in my first post so I would think something would set if fuel was lacking to the engine which seems is not the case. So as some of us said it has to be the tune.

Yeah, I'm leaning on it being something with the tune. I used to run a dhp 1.0 and it used to pick up quick but too much kr under accel & wot which meant too much timing and too lean. Thats why I went with a "tune by scan" starting with a stock bin via email. It now has no kr but as you can see it can be much better. I dynoed it a local speed shop 3 pulls @$60 weekend special event. They quoted me $320 for a 3 hour dyno tune. I'll have to put some $$ aside for that one, but the guy there said it should be no problem getting it to where it should be at with the mods I have.

Resurrection of a year old thread! Lol

stock they put down between 190-195. You don't have headers or a PEMs, 1.8 rockers don't do crap (at least not on my car). Do you have a colder stat?

You really need some headers

I been running a 180* stat since I installed my first dhp pcm from zzp when they used to carry them.

Yes but you have a built motor thats like comparing apples to oranges, but those are impressive #'s
