Default Retuned & added TSP 100mm MAF, FTP 104 and ATI 10% UD

I had RPM install an ATI 10% UD Pulley, a 100mm TSP MAF replaced the stock 75mm and 104 FTP Lid replaced the SLP Lid, along with a retune. Added 12rwhp and 10rwtq. The car pulls harder and it seems like she enjoys breathing ?

Big thank you to the guys at RPM, logged about 20 miles of real world driving with the tuner, adjusted to my driving style. Getting a full weight car into the 10's and it having perfect street manners ain't easy, but it can be done with the right people.

The Engine is a TSP 404 LQ9, dinky little 232/234 T2 Cam, TEA Stg 2 243 heads, FAST 92/NW92, 1-7/8 Kooks...

Glad you posted this, was thinking about adding the TSP 100mm maf and 104mm lid to my 402. Glad to see you picked up some power

We're thinking it maybe a converter issue? It showed up on the original build dyno/tune. I have a second guess at it, that's about the peak of the cam, I kind of have a gut feeling that's the choke point of the less than .6 lift 232/234 cam... I maybe wrong

Shouldn't be, TEA Heads new springs less than 18 months old, less than 3500 miles.

I agree! Not bad numbers but something is off in the valvetrain setup/geometry...
