ls lacks power

[spooncb7]

i got a 98 b18b1 in my bubble with an obx intake mani n a 4-1 header with no o2 sensor. it used to pick up great up to 130 or so n now it seems to lack power in the top end n not climb as fat as it used to

tunning the car is not gonna bring it back to its original state.

Compression check
leakdown check
valve adjustment
timing

x2 if it slowed down something is wrong with it. It's not like it was tuned and the tune randomly turned into a stock one so it slowed down randomly. Thats a pretty basic setup to tune. I'd do more work to it before getting it tuned.

..hopefully you did plugs too..lmao make sure u take it back to basic first, air filter/intake filter..fuel system flush. iso fuel cleaner works..never octane booster..
