I Need Help
I had my Jet hot LT's installed a few weeks ago but havent driven the car much because of a small leak, here is my problem. I drove it around a little last night and when im at low speeds (10-15 miles an hours) i will hit the gas and my car just does nothing for 2-3 seconds. Its like im not even pushing the pedal then it revs and goes. Any ideas on this guys? all i have done is the LT's but here is a list of all my new parts. Opti less than 5000 miles, plugs wires new, fuel pump and filter new, coil and ICM new, ignition switch new. I didnt notice this happening untill after i put in the LT4 knock mod. but i dont think this would have anything to do with it. the car is a 94 a4 and the trans has been rebuilt as well, thanks for any help !

OK now i have a beef with some of the peoples advise with tunes on just header only cars, i replaced the TPS last night and then went out for a drive nothing changed. i noticed the temp was getting higher than normal so i put the 160 thermo back in and then pulled out my hypertech. yes i know its not all that great but i forgot i had uninstalled it before i took it to the shop. well installed it back on and got all my throttle response back and no More hesitation. so i going to say you do need a tune with just LT install

As for a tune, you could pick up 10rwhp from a tune on a bolt-on LT1.

Besides that, I wouldn't mess with that Hypertech and I'd get a real tune.
