My tuner said it was my exhaust causing the break up at the top around 6500rpms. the first graph was at 5psi and the HP line was a lot smoother up top than the new dyno at 9psi.

my setup is
Stock JDM GSR
skunk2 IM
Peakboost FTW kit
t3/t04e 57 trim
650cc injectors
walboro 22lph
3"dp - high flow cat -2 1/2" with resonator
hondata s300

this is my old graph at 5psi[IMG][/IMG]

this is my new graph at 9psi[IMG][/IMG]

Get a new tuner

^ Agreed, thats not a exhaust problem causing that.

Air fuel looks good, check ignition, igniter, plug gap and so on. Timing could be shitty.

Your graph has Parkinsons.

This sounds like a great place to start.

ok well my spark plugs are gapped at .028 but i will recheck those tom. but if it were my plugs wouldnt it be sputtering? cause its not at all.

It looks like spark blow out. check your dist, coil, cap, rotor.

Also what gas are you using?

Try a smaller spark plug gap, it helped cure my break up issues.

check the ignition control module (ICM) i had a similar problem on my na gsr, and it turned out to the a bad icm/dizzy

When a customer has a situation similar to yours, I usually replace the customer's distributor assembly to try and diagnose if the issue is related to the distributor assembly....

DO NOT use aftermarket discount autoparts distributor assemblys. OEM honda only!

Yep thats a textbook missfire uptop to me. Check your ignition timing to verify its correct to what its set at, try resister plugs with that much power, i wouldnt see why 9psi w/ t3/t4 be blowing the spark out on a .28 gap. Like others say, swap distributers as well to. Also check to see if your wastegate dump tube isn't near your compressor inlet.

I will make sure to check my plugs. i will prob get new ones because i have had these for about 2 months and during both tune sessions. and if that doesnt correct it i will go to the dizzy and work my way from there thanks guys.

and my tuner is roy and arron from ultrapower garage. super good guys and know what they are doing. They also told me that when they were doing it that they tried to mess with timing to correct it and it didnt and lost a little power so thats why they said its my exhaust. but im thinking my plugs so i will check the color and gap today.
