Ok so I boosted the LSv, put a new competition Iron Man clutch in it drove 300 miles just to see what its got and the car **** on me. It acts like it might have a boost leak somewhere, but it won't barely build 5 lbs. and it's not hitting vtec. It just hesitates after about 4psi of boost. I know I probably need to re-gap my plugs to 30ish, but I didnt know if it would make that big of a difference.

I'm running all stock internals, garrett t3 turbo, tubular manifold, pricision intercooler, 450 dsm injectors, and a p72 on Chrome with a street tune for 8.8lbs. I wasn't sure if the ECU tune would eliminate the MAP sensor missing link ordeal or if I needed one regardless. Any help would be greatly appreciated. If it's not the missing link I'm guessing there is a boost leak I haven't found yet or the spark plug gap issue. Either way its struggling with boost and not hitting vtec as far as I can tell. I had a poormans type r not hit vtec on me one time when it came unplugged and it feels about the same, just alot of hesitation.

is it throwins any codes? the car was tuned for that exact setup?

the computer was tuned for a GSR, but the same exact injectors and everything. No CEL... Some people think it is because I hooked the exhaust up, but I don't think it would make this big of a difference. It is downpipe into flex pipe into high flow cat into 2.5" straight pipe Apexi Worldsport2. I can't even get it out right now for all the snow so I'm just trying to get a couple ideas of what it could be.

Does anyone know if the spark plugs being gapped around 50 would make it hesitate?
I never gapped them from where they were at all motor.

you should not be running a missing link with crome.

A missing link is for someone running a FMU that has to hide boost so the map sensor cant read it you shouldnt have a Missing link with a chipped ecu. Your plugs should be gaped at 23-27. NOT 50. you obviously have no clue what your doing here. And from what you are saying your car was never tuned. you bought a ecu that had someone elses tune on it?? thats a NO NO. you need a tune if you havent gotten a tune for your car Cant be using someone elses. same setup or not thats just laziness.

Yea thanks for the help man, I'm not retarded, I have had a turbo car before. I'm just asking questions cause I didn't figure everyone would be a douche bag about it. I don't have a bunch of money to throw at my cars like most so give me a break man. I just stated that I hadn't had a chance to look at it for all the snow up here so i figured I would ask around. I fixed a major boost leak today and it pulls fine now. I just need a straight answer on what exactly not gapping your plugs properly would do. Blow the spark out and cause detonation?

wow.
