TUNING HELP PLEASE!

[WITCYOTE]

So I got my car dyno tuned this past Friday. Made 410/370 on a 93 race tune. Only mods are JLT intake and the tune. Every time I start the car now, it revs up, but then the RPMS immediately drop til the car almost dies then comes to about 500rpm. What could be causing this? Thanks in advance.

Who tuned it? Has it been like that ever since they tuned it or did it just happen? Did you ask the tuner?

Mo from Lsxkilr, he said to give it time for the ecu to adapt but it's been doing the same thing for the past 4 days

Do you have any mechanism to log?

 

[WITCYOTE]

Have an x4 but have never data logged

Make sure he tuned for the jlt intake,that will make your car do just what its doing,a data log would confirm.

Will do, I'll ask him if I take it back... and I'll check for leak on lunch

Well, tightened everything down on the car, was good for the first time I started, but second time did the same thing

Re-install the MAF sensor and make sure it is flush.
