Actually looks pretty decent (some minor timing corrections). Looks like you were just experiencing the traction control kick in. Your low pressure fuel pump is struggling to keep up (under 50psi) even on just pump gas though. If you're considering trying more aggressive maps or an ethanol mix you may want to consider swapping it out. |

It's due to an old and aging fuel pump. I mean it might not fail if you turned the tune down but given you're not even running any ethanol and it's pretty low I'd say you should get a new or upgraded one.

I don't know about aftermarket OE ones, but there are plenty of upgraded pumps out there though.
There stage 2 and stage 3 setups that use Walbro pumps. I run a stage 2 Fuel-It setup because I also run an ethanol blend. If you're not planning to run ethanol or a lot of HP a stock pump would be fine. |

Ive had a Fuel it Stage 2 (bucketed) for 3 years now and its run perfect. Excellent customer service from them also, I had a question on a Saturday about an adapter size and they answered the phone immediately.
If you are gonna replace the pump, might as well upgrade it so you can run an ethanol mix down the road. |
