1le with pd supercharger and rev match issues

biker2k · 11-25-2020, 11:53 AM

anyone here with a pd blower experience drivability issues when rev match is on and it goes away when rev match is off?

Im not so sure this is a blower specific issue, there are several reports of rev match on causing drivability issues with the 1les once they have a tune on them. I have an issue where under partial throttle it feels like its towing an extra 2000 pounds for a few seconds then will actually accelerate properly. I just leave rev match off at this point

yes mine is like its struggling then bang its back..
its mind boggling, i have been dealing with this for a year and change and just realized it goes away with rev match off... i always drive with it on and i thought it was in my tune, like i had a bad tune or something..

i cant believe there is no solution for this

I have talked to a few people who have gotten retuned by someone else and they say the problem went away but I don't want to throw money at a maybe fix

biker2k · 11-26-2020, 10:45 AM

so pray knows about it and couldn't fix it?
my tuner also said he could maybe fix it....
apparently the 1le's have a table that hp tuners cant access related to when rev match is on...

I’ve traced it down to the ported 95mm throttle body. Don’t have the issue with the stock tb. Tried a soler performance and a tick ported 95mm same problem. Engine is being built now with a 103mm throttle body hoping it resolves the issue.

my 95 is non ported and ive swaped out stock tb and still does it

I have a Pray tuned car with ported TB/IM and E85...no rev match issues.

The torque tables need to be adjusted. That’s 100% torque management.

Find a tuner who understands that and your problem will be solved.

No issues with rev match on my car.

My car was tuned by SS LSX performance outside of Charlotte and have had zero issues with rev match. My car is FBO with a cam...

I think it’s something overlooked in the tune
