new engine stumbles at wot

[payupsucka]

put a new 306 in the car took it out for its first ride and , when you slowly get on the gas the motor pulls nice not stuttering or anything, but when you nail it the motor gets to about 3500 4 k and fall on its face like its on the rev limit or something. my guess is its the tps sensor what do you guys think?


thanks in advance for the help
