with a 8.2 1/8 it seems like you losing something after the 1/8 mark. I recently ran 12.9 with 8.4 1/8. Maybe You just need your shift points to be adjusted. hope this helps

ya what kind of tune, a dyno or mail order? A dyno tune would be a good start, or find a different tuner.

car has an issue with power. be it the tune or something else. i'd expect those mods to easily generate a high 11 sec slip.

tranny may be slipping? You are missing some mph for sure

Trans just been refresh. I put it in last sat. Bad trans ran a 13.5 and 1/8 8.8. So I guess its in the tune. I just hate twice spending money twice.

defintely seems like tune issue that should be an 11 second car for sure.

yeah youre definitly way down on power the whole way down the track. you could have a bad maf, bad knock sensor, bad o2 sensors or just a plain bad tune.
