My dyno plot - Bolt on's, 91 Octane and Dyno Jet - Weird numbers....
Good afternoon gents. I recently did my dyno this week and got some odd ball numbers I feel.
Mods: JB4 G5 Map #5 VRSF Downpipes ER Charge pipe TiaL BOV BMS DCI My torque curve is insane, this is a fourth gear pull as well. Now, I feel like my HP numbers are kind of low, could this be due to not running my intercooler currently? The worst part is, I didn't have a cable to log my dyno pulls when I was there, so I can't really see whats going on. Do these numbers look accurate for these mods?

numbers seem low should be more in the low, to low mid 400 so let me ask this
did you do any pulls to let the JB4 adapt what version are you running? hex 21 or greater?

I did a bunch of pulls, I had installed it a month or so ago. I am running only 91 octane gas, no E85 up here. I don't know which version I am running due to not having the cable for my JB4

i would say get a cable and do a log and send to Terry looks like there might be something off but, hard to say with no log.

Nope. Was a sad day for not having the cable, but the dyno was only $50.00 for three pulls.

Nope. He is on 91 with stock FMIC. He isn't going to make mid 400's. 330 seems reasonable. You need good gas to make good power. Switch to e85. +80whp easily.

350rw is not unreasonable for 91 octane. It can be pretty bad. But without a datalog it's hard to determine why it isn't say 370rw like I've seen from others on 91 octane with similar mods.

I would love to run E85! It's extremely hard to source in Canada. None in my province

Can you source meth? That would be able to bring you into the 400whp club.

I haven't been on the dyno but I would expect the same numbers. I'm actually surprised at the torque being that high. I have essentially the same mods.

My charge pipe has two bungs and I already have the DevilsOwn black 2.5 Gallon race tank with level sensor installed. Just waiting to do either intercooler before meth!

Numbers seem about right considering the potential heat soak, timing drops, and 91 octane. |

I just need to source the rest of the kit. I don't really know exactly what I need; and my main concern is if I am capable enough to do the install my self. This is something I do not want to have screw up!
Something acted funny with my vehicle last night actually. I was driving home from work (12 minute ride) and I never got "on it" should I say. Near the end of my ride, after a light I went to pass a car and tossed into sport, banged down a gear and floored it. The RPMS crawled up and I couldn't hear any boost. All of a sudden, CEL ignited and I turned into the lane after letting him pass. I than put into regular D and back into Sport. With the CEL still illuminated I tried the throttle again, this time it let me boost like normal until I got home. I turned the car off and back on and the CEL was gone. It felt as if I was miss firing almost, does this engine have a common issue with the coilpacks? I only have 38,000 km's (23,000 miles).

Those torque numbers don't seem correct to me. I'm FBO with 93oct fuel and I made 378hp and 417tq (no meth, JB4 was well adapted). I would think my car would make more just having the intercooler and better gas.
