PE at 90% throttle to be carb legal

I'm gonna be looking at this as soon as I'm home. Thanks.

Ok. I just got home from being away from work. I turned the knock limiting off and everything is PERFECT! I have ZERO hesitation now!:clap2: At low RPM, full throttle pull I'm seeing 1 degree of knock then starts going into negative. That 1 degree was obviously shutting my throttle and causing my hesitation with the knock limiting. The car drives COMPLETELY stock, besides the new exhaust tone it now has with the crackling and popping then becomes a complete animals once you step on the gas. From my experience, excellent job Whipple on the calibration!

Glad to hear you have it sorted out....off topic, how are those Indy 500s hooking for you.

Well it's been cold and snowing since I put them on so i haven't really had a good chance to try them out. Heard a lot of good about them so I'm excited for some warm dry pavement...lol

Small update. So logged the car on the dyno today. She made 681whp and 540TQ on Whipple tune which is pretty awesome! Down low between 2000 and 3500 if I floor the throttle she do have a small delay/stumble due to power enrichment. Not a big deal at all. Fuel trims and AFR is very good. One thing which I thought was crazy is that I'm making 22* timing up top! Lol...even though the engine and ECU is happy and adding timing, that seems like a lot of timing for pump. This is just a personal preference but I wanna keep it around 17*. Overall very happy!

I'll try and post the dyno sheet later. Rev to 7500, 94 fuel. Again stock Whipple cal.

It was a dynojet. STD correction 5...the stock 3.75 pulley

Here is the graph. You can see the hesitation in the graph when he first hits the throttle then on the second pull the car pulls timing up top due to knock.

Sorry trying from my phone and it says the file is too big...I'll try again later.
